The picture shows a ball rolling up a ramp.

Question

Which statement best describes the motion of the ball?

(1 point)
Responses

The speed of the ball is increasing.
The speed of the ball is increasing.

The speed of the ball is decreasing.
The speed of the ball is decreasing.

The motion of the ball is constant.
The motion of the ball is constant.

The motion of the ball is stopping.

Answer 1

Based on the description of a ball rolling up a ramp, the best statement to describe the motion of the ball is:

The speed of the ball is decreasing.

As the ball rolls up the ramp, it is moving against gravity, which causes it to lose kinetic energy and slow down until it eventually stops momentarily before rolling back down.

Answer 2

a graph shows the velocity and time of a horse, the first dot shows 5 meters per second (or the velocity) in 5 second, 10 meters per second in 10 seconds, 15 mps (meters per second), in 15 seconds and so on
Which statement is true about the horse's motion?

(1 point)
Responses

The horse increased its acceleration during this portion of the race.
The horse increased its acceleration during this portion of the race.

The horse decreased its velocity during this portion of the race.
The horse decreased its velocity during this portion of the race.

The horse maintained a constant acceleration during this portion of the race.
The horse maintained a constant acceleration during this portion of the race.

The horse maintained a constant velocity during this portion of the race.

Answer 3

Based on your description of the graph showing the velocity of the horse increasing linearly over time (from 5 m/s to 10 m/s to 15 m/s), the best statement to describe the horse's motion is:

The horse maintained a constant acceleration during this portion of the race.

This is because the increase in velocity over equal intervals of time indicates a constant acceleration.

A ball rolls 50 centimeters away from the table.
A ball rolls 50 centimeters away from the table.

A skateboard moves 2 meters per second.
A skateboard moves 2 meters per second.

A student walks 20 meters down the street.
A student walks 20 meters down the street.

A car travels east at 55 kilometers per hour.

Answer 5

The statement that is an example of velocity is:

A car travels east at 55 kilometers per hour.

Velocity is defined as the speed of an object in a given direction, which is why this statement qualifies as an example of velocity. The other options provide distance or speed without directional components.
