Front

What term describes the change in position of an object over time?

Back

Motion

Front

What is the term for the distance traveled by an object in a given amount of time?

Back

Speed

Front

What happens to the speed of an object when a net force is applied in the direction of its motion?

Back

The object will speed up.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is the effect of friction on the motion of a toy car on different surfaces?

Back

Friction slows down the motion of the toy car more on a thick rug than on a smooth tile.

Front

What is the term for the rate at which an object changes its velocity?

Back

Acceleration

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant speed in a straight line.
