What three forces are always in effect?
Answer:The gravitational force is defined in Uniform Circular Motion and Gravitation, electric force in Electric Charge and Electric Field, magnetic force in Magnetism, and nuclear forces in Radioactivity and Nuclear Physics. On a macroscopic scale, electromagnetism and gravity are the basis for all forces.

The graph represents velocity over time.
A graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). A line runs from 0 seconds 2 meters to 100 seconds 22 meters.
What is the acceleration?
–0.2 m/s2 I did it on edge 2020
Answer:
the answer is C
Explanation:
i got it wrong the first time because the answer above says -0.2 but its actually 0.2

An object travels at 3.06 m distance with uniform acceleration in this interval it's velocity increases by 0.18 and it's average velocity over the interval was 0.34 m/s what is the acceleration?
Given that,
Distance travelled, d = 3.06 m
Final velocity, v = 0.18 m/s
Average velocity of the object, V = 0.34 m/s
To find,
The acceleration of the object.
Solution,
Let t is the time in which it covers distance d. Average velocity is given by distance covered divided by time.
[tex]V=\dfrac{d}{t}\\\\t=\dfrac{d}{V}\\\\t=\dfrac{3.06}{0.34}\\\\t=9\ s[/tex]
Let a is the acceleration of the object. Using equation of motion to find it :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0.18-0}{9}\\\\a=0.02\ m/s^2[/tex]
So, the acceleration of the object is 0.02 m/s².
A car possesses 20 000 units of momentum. What would be the car's new momentum if its mass was doubled
I'm
Answer:
40 000 units of momentum
Explanation:
Assuming that the mass is doubled and the velocity stays constant the new momentum will be doubled the original momentum.

What is force & how is it measured?
Answer:
Force is measured using either the English System of Measurements or the International System of Units A force can cause an object with mass to change its velocity It is measured in the SI unit of newtons and represented by the symbol F.
Explanation:
A 5 kilogram block is dropped from a height of 3 meters and falls straight to the ground. What is the work done by the force of gravity?
Answer:
Workdone = 147Nm
Explanation:
Given the following data;
Mass = 5kg
Height = 3m
We know that acceleration due to gravity is 9.8m/s²
First of all, we would find the force applied;
[tex] Force = mass * acceleration [/tex]
Force = 5*9.8
Force = 49N
Now, to find the workdone;
[tex] Workdone = force * distance [/tex]
Substituting into the equation, we have;
Workdone = 49 * 3
Workdone = 147Nm
