1) Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.
For Example : A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.
2) Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
For Example : A child at the top of the slide
3) KINETIC ENERGY
Kinetic energy is the kind of energy present in a body due to the property of its motionIt can be easily transferred from one body to anotherIt is relative with respect to natureFlowing water is one of the examples of kinetic energyPOTENTIAL ENERGY
Potential Energy is the type of energy present in a body due to the property of its stateIt is not transferableIt is non-relative with respect to natureWater present at the top of a hill is an example of potential energy(make sure to draw a table and write them separately)

What quantity is measured on the x-axis of a position vs. time graph.
distance

velocity
position
Answer:
Velocity
Explanation:
A skydiver reaches terminal velocity. Then he opens his parachute.
What happens to the skydiver as the parachute opens?
Answer:
Explanation:
Remark
He's pulled upwards by the parachute. The formula is given below. Details are found searching for terminal velocity.
[tex]V_t=\sqrt\frac{2mg}{\rho A C_d}[/tex]
Whatever that calculation turns out to be, a person has to be going a whole lot slower before he can safely hit the ground. The parachute is designed so that the person will be slowed very quickly to a safe velocity so when he hits the ground the impulse will not be as great as it could be. The force that the parachute delivers acts upward and opposes the force of gravity which is a downward force.

Answer: white shirt-reflect
top hat- reflect
elepahnt- i think absorb im quite sure
Explanation:
Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. Different shirts with different colors will absorb light of different wavelength. Black shirt will absorb all colors of light while white shirt will reflect all colors of light. thats why on a hot day you wouldnt want to wear a black t shirt.

The earth gravity field strength in the south pole is less than the north pole. Explain
Answer:
Your weight is the combination of all the large-scale, long-term forces on your body. While the earth's gravity is by far the strongest large-scale force, it is not the only one. What you experience as "something pulling you down" is actually the total of all the forces and not just gravity. The four dominant large-scale,

Use and describe the use of rules and measuring cylinders to find a length or a volume
Answer:
To be honest, if you’re preparing for your IGCSEs, you should really know how to use a ruler, but I’ll explain it anyway.
A ruler is a flat object, usually rectangular, with markings along one or more of its straight edges.
These markings show us how long something is. It can only be used to measure other straight lines. If you want to measure something, hold the ruler against it, aligning the start of the edge of the object with the 0 on the ruler, and read off the ruler how long it is.
Explanation:
The volume of the cylinder can be found by putting the value of length and height in the formula πr²l. Length can be measured by using a ruler.
What is volume?
An object's volume is a measurement of the amount of space it occupies in three dimensions. This indicates that an elephant's volume is more than a mosquito's volume.
Since gases fill their containers to the brim, their volume is equal to the container's internal capacity. Liquids are routinely measured using containers with specified internal shapes or ones with predetermined volumes.
A ruler is a flat device with marks along one or more of its straight edges. It is typically rectangular.
The length of anything is indicated by these markers. Only other straight lines can be measured using it. If you want to measure something, place the ruler against it, line up the object's beginning edge with the number 0, and then read the length of the ruler.

ignoring friction, what is the mass of an object accelerating at 1.8m/s2 to which an unbalanced force of 42 Newtons has been applied?
Explanation:
Newton's second law:
F = ma
42 N = m (1.8 m/s²)
m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question the mass of an object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied is ,
Using Newton's second law force is given as
F = ma
42 N = m (1.8 m/s²)
m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.

A slab of thermal insulator is 200cm square in cross section and 5cm thick.If thermal conductivity is0.50 and temperature difference is 150 what is the heat flow through the slab in 2 days
Answer: 5184 kJ
Explanation:
Given
Area of cross-section [tex]A=200\ cm^2[/tex]
thickness of slab [tex]t=5\ cm[/tex]
thermal conductivity [tex]k=0.5\ W/m-K[/tex]
temperature difference [tex]\Delta T=150\ K[/tex]
Heat flow is given by

500cm3 of water is to be jeated from room temperature 28oc to 100oc in order to prepare ahot cup pf coffee. What os the minimum heat required
Answer:
The minimum heat required is 171626 joules.
Explanation:
By First Law of Thermodynamics, the amount of heat ([tex]Q[/tex]), in joules, is equal to the change in internal energy of water. The minimum heat required is the sensible heat necessary to heat up the water. That is:
[tex]Q = \rho\cdot V \cdot c\cdot \Delta T[/tex] (1)
Where:
[tex]\rho[/tex] - Density of water, in kilograms per cubic meter.
[tex]V[/tex] - Volume of water, in cubic meters.
[tex]c[/tex] - Specific heat of water, in joules per kilogram-degree Celsius.
[tex]\Delta T[/tex] - Change in temperature, in degrees Celsius.
If we know that [tex]\rho = 1000\,\frac{kg}{m^{3}}[/tex], [tex]V = 5\times 10^{-4}\,m^{3}[/tex], [tex]c = 4186\,\frac{J}{kg\cdot ^{\circ}C}[/tex] and [tex]\Delta T = 82\,^{\circ}C[/tex], then the minimum heat required is:
[tex]Q = 171626\,J[/tex]
The minimum heat required is 171626 joules.
Experiments have shown that a magnetic Just sitting next to a wire produced no current flow through that wire. However, If the magnet is____________ then a current is Induced the wire. The_____________ the magnet moves, the______________ the Induced current.
Answer:
Experiments have shown that a magnetic Just sitting next to a wire produced no current flow through that wire. However, If the magnet is brought close to the coil of wire or a relative motion is established between the magnet and the wire then a current is induced in the wire. The closer the magnet moves, the more the Induced current.
Explanation:
A magnet sitting next to a wire would not induce a current in the wire because the magnetic lines of force of the magnet are not in relative motion to the wire.
If you move a magnet close to a wire, the electrons will move thus generating current.
⦁ A body has weight 10 N. How much force is required to move it vertically upward with an acceleration of 3 ms-2?
Answer:
Force = 3.06 Newton.
Explanation:
Given the following data;
Weight = 10N
Acceleration = 3m/s²
To find the force required;
First of all, we would determine the mass of the body.
Weight = mass * acceleration due to gravity
We know that acceleration due to gravity is equal to 9.8m/s².
10 = mass * 9.8
Mass = 10/9.8
Mass = 1.02 kg
Now, we can find the force required by using the formula below;
Force = mass * acceleration
Force = 1.02 * 3
Force = 3.06 Newton.
