Force and Motion STAAR Review

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces in contact. It occurs when objects rub against each other.

Front

What happens when a force is applied to an object?

Back

A force can make an object move, slow it down, or stop a moving object.

Front

How does the weight of an object affect friction?

Back

Heavier objects generally have increased friction with the surface they are on, making them harder to move.

Front

What is a spring scale used for?

Back

A spring scale is used to measure the amount of force applied to an object.

Front

Why is it important to use the same object in an experiment?

Back

Using the same object helps ensure that the results are consistent and that any changes observed are due to the variable being tested.

Front

What is the effect of a rough surface on friction?

Back

A rough surface increases friction, making it harder for objects to slide over it.

Front

What is the relationship between force and motion?

Back

Force is necessary to change the motion of an object, whether that means starting, stopping, or changing direction.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if it is changing its position relative to a reference point.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion, especially when they are falling.

Front

How can the type of surface affect the distance an object travels?

Back

Different surfaces create different amounts of friction, which can affect how far an object moves when pushed.
