Net Forces

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is gravitational force?

Back

The force that attracts two bodies towards each other, such as the force that keeps planets in orbit around the sun.

Front

What happens when forces are balanced?

Back

The net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the larger force.

Front

What is the unit of force?

Back

Newton (N) is the unit used to measure force.

Front

What is an example of a balanced force?

Back

A book resting on a table is an example of balanced forces acting on it.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked is an example of unbalanced forces.

Front

What does it mean for an object to accelerate?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to unbalanced forces.

Front

What is air resistance?

Back

A force that opposes the motion of an object through the air.

Front

What is friction?

Back

A force that opposes the relative motion of two surfaces in contact.
