What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

How do you calculate net force when two forces are acting in opposite directions?

Back

To calculate net force, subtract the smaller force from the larger force and indicate the direction of the larger force.

What is an example of a contact force?

Back

An example of a contact force is friction, which occurs when two surfaces rub against each other.

What is an example of a noncontact force?

Back

An example of a noncontact force is gravity, which acts at a distance without physical contact.

What is friction?

Back

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

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

Back

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