Force and Motion STAAR Review

Front

What is force?

Back

A force is a push or pull that can cause an object 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 gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is needed to move it.

Front

What is a spring scale?

Back

A spring scale is a tool used to measure the force of an object, typically in units of newtons.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest will stay at rest, and an object in motion will stay in motion.

Front

What is the effect of a constant force on an object?

Back

A constant force will cause an object to accelerate in the direction of the force.

Front

What happens when two forces act in opposite directions?

Back

When two forces act in opposite directions, they can cancel each other out, resulting in no motion.
