Forces Flashcard Practice

Front

What is a force?

Back

A force is a PUSH or PULL on an object.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the forces are combined.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and opposite, causing a change in motion.

Front

What unit is used to measure force?

Back

The unit of force is Newton (N).

Front

If two forces of 20N and 15N act in the same direction, what is the net force?

Back

The net force is 35N in the same direction.

Front

If a 10N force acts to the right and a 5N force acts to the left, what is the net force?

Back

The net force is 5N to the right.

Front

What happens to an object when the net force is zero?

Back

The object remains at rest or continues to move at a constant speed.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is gravity?

Back

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