Force and Motion STAAR Review

Front

What is force?

Back

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

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 grams or kilograms.

Front

How does mass affect motion?

Back

Objects with more mass require more force to move the same distance as lighter objects.

Front

What is a spring scale?

Back

A tool used to measure the force applied to an object, typically in newtons.

Front

What is the relationship between force and distance?

Back

When a constant force is applied, the distance an object travels can depend on its mass.

Front

What is the importance of conducting multiple trials in an experiment?

Back

It helps to ensure that the results are reliable and not due to random chance.

Front

What is a controlled variable?

Back

A factor in an experiment that is kept constant to ensure a fair test.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion, making it harder for objects to move.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be an increase or decrease in speed.
