Test Review Force and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What are unbalanced forces?

Back

Forces that cause a change in the motion of an object because they are not equal in size and opposite in direction.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be a change in speed or direction.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the greater the force needed to change its motion.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does the slope of a distance-time graph represent?

Back

The speed of the object.
