Question

Find all of the examples of an object that is accelerating.


*The train traveled at a constant 55 mph down the track.

*The car got very hot as it sat in the parking lot.

*The motorcycle traveling east had to stop at a stop sign and wait for the truck to pass.

*The runner ran at a constant 4 mph around the oval race track.

*A car that is stopped at a traffic light starts moving when the light turns green,

Answer 1

Explanation:

the example which shows an object accelerating is:

A car that is stopped at a traffic light starts moving when the light turns green.

Answer 2

*The motorcycle traveling east had to stop at a stop sign and wait for the truck to pass.

*The runner ran at a constant 4 mph around the oval race track.

*A car that is stopped at a traffic light starts moving when the light turns green,

Explanation:

Any kind of change in the velocity of motion is called acceleration.

Velocity comprises of both magnitude and direction, so change in any of these parameters with respect to time will account for acceleration.

• The motorcycle traveling east had to stop at a stop sign and wait for the truck to pass.

While the motorcycle travelling east had to stop to come to rest it had to decelerate to lower down its speed before it finally comes at rest.

• The runner ran at a constant 4 mph around the oval race track.

When a runner runs at a constant speed on an oval path his speed is constant but his direction is changing according to the path of track which it follows so the overall velocity is changing with time and hence there is an acceleration in motion of the runner.

• A car that is stopped at a traffic light starts moving when the light turns green

The car that is at rest has to come to motion which means the car has to change its velocity with respect to time to come to motion introduces an acceleration to the motion.
