Please HELP ME If the motion of an object changes, what must be true about the forces acting on that object?

Answers

Answer:

If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. ... Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

Explanation:

If the motion of an object changes, the net force on the object is greater than zero or the forces acting on the object is unbalanced.

According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object. The object will move in the direction of the applied force.

When the net force on an object is zero, the object will be remain at rest.

However, when the net force on object is greater than zero, the object will move in the direction of the greater force.

Thus, we can conclude that if the motion of an object changes, the net force on the object is greater than zero or the forces acting on the object is unbalanced.

a. he is accelerating

b. he is covering a greater distance in each consecutive second.

c. he is moving with a constant speed (on average).

Answers

Answer: c

Explanation: for #5 it can still be moving, just at a constant speed; therefore, it will be c.

If an object has an acceleration of 0 m/s2, then one can be sure that the object is not changing velocity.

If car A passes car B, then car A must be moving faster than car B, but not necessarily accelerating.

The not consistent with a car that is accelerating is a car is moving at a high speed.

A fullback is running down the football field in a straight line. He starts at the 0-yard line at 0 seconds. At 1 second, he is on the 10-yard line; at 2 seconds, he is on the 20-yard line; at 3 seconds, he is on the 30-yard line; and at 4 seconds, he is on the 40-yard line. This is evidence that he is moving with a constant speed (on average).

What is Acceleration?Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). Speed is the distance covered in a unit of time while acceleration is the rate of change in speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity while acceleration is a vector quantity.

(2) Far from simply brightening our day, engagement with the natural world through social media may actually be helping to save our planet.(3) Both individuals and organizations increasingly use social media to raise awareness of environmental issues and support conservation research. (4) A research article, news report, or photograph that goes viral can reach a global audience in a matter of minutes, connecting interested people with each other and allowing for a nearly immediate exchange of ideas. (5) In 2012, for example, a high school student posted a picture of an unusual lizard he saw in a local park to a nature-focused social network, where other members identified the lizard and noted how far it was from its known habitat. (6) This in turn became useful data for researchers studying these lizards and their changing ecosystem.(7) The global audience provided by social media can also have a considerable economic impact for environmental causes. (8) Consumer pressure following the viral circulation of photos of turtles and other marine life injured by plastic drinking straws, for example, has led major corporations to seek more environmentally sustainable options.
