EOG Prep: Force and Motion 5th Grade NC.5.P.1

Front

What is friction?

Back

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

Front

What type of force is friction?

Back

Friction is a contact force.

Front

What happens to an object when unbalanced forces act on it?

Back

The object's speed or direction changes, or it may start moving if it was at rest.

Front

What is a contact force?

Back

A contact force is a force that touches an object to make it move or change direction.

Front

What is a non-contact force?

Back

A non-contact force is a force that does not touch an object to make it move or change direction.

Front

What happens to an object when balanced forces act on it?

Back

The object will either remain at rest or continue moving at the same speed.

Front

Can you give an example of a contact force?

Back

An example of a contact force is friction between a sliding book and a table.

Front

Can you give an example of a non-contact force?

Back

An example of a non-contact force is gravity, which pulls objects toward the Earth without touching them.

Front

What is the effect of friction on motion?

Back

Friction slows down or stops the motion of an object.

Front

What are the two types of forces?

Back

The two types of forces are contact forces and non-contact forces.
