What happens to the speed of a ball thrown straight up as it rises and falls?

Back

The ball goes slower and slower as it goes up, stops, and then goes faster and faster as it comes down.

Define 'force' in the context of motion.

Back

A force is a push or pull that can cause an object to accelerate, decelerate, or change direction.

What is the relationship between mass and force required to change an object's motion?

Back

The greater the mass of an object, the more force is required to change its motion.

Explain the concept of acceleration.

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

What is the effect of gravity on a thrown object?

Back

Gravity pulls the object downward, affecting its speed and direction as it rises and falls.

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
