Balance forces are two forces acting in opposite directions on an object, and equal in size.

Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction.

In physics, the Net force is the overall force acting on an object.

To calculate net force, the body is isolated and interactions with the environment or other constraints are represented as forces and torques in a free-body diagram.

Average speed is a rate. In kinematics, a rate is always a quantity divided by the time taken to get that quantity (the elapsed time).

Sinceaverage speed is the rate position changes, average speed = distance traveled/time taken.

Static friction is the friction that exists between a stationary object and the surface on which it's resting.

A frictional force occurs when you try to push an object alongside a surface.

# data[].attributes.body
Kinetic friction is a force that acts between moving surfaces. An object that is being moved over a surface will experience a force in the opposite direction as its movement.

The magnitude of the force depends on the coefficient of kinetic friction between the two kinds of material.

# data[].attributes.body
the resistance that one surface or object encounters when moving over another.

the action of one surface or object rubbing against another.
