Force and Motion STAAR Review

Front

What is force?

Back

A force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

Front

How does mass affect motion?

Back

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

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

What happens when a constant force is applied to an object?

Back

When a constant force is applied, the object will accelerate in the direction of the force.

Front

What is the relationship between force and distance?

Back

The greater the force applied to an object, the farther it will move, assuming mass remains constant.

Front

What is an example of a balanced force?

Back

When two people push on opposite sides of a box with equal force, the box does not move.

Front

What is an example of an unbalanced force?

Back

If one person pushes a box harder than another person pulls it, the box will move in the direction of the stronger force.
