Force & Net Force

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 net force?

Back

The total force acting on an object after all the individual forces are combined.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal and can cause an object to start moving, stop moving, or change direction.

Front

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

Back

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

Front

What is an example of an unbalanced force?

Back

A soccer player kicking a ball, causing it to move.

Front

What is friction?

Back

A force that opposes the motion of an object, often caused by contact with another surface.

Front

What is gravitational force?

Back

The force of attraction between two objects due to their mass.

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is needed to change its motion.
