Overview
Force and motion explain how objects start moving, stop, change speed, change direction, and change shape. Motion is affected by balanced forces, unbalanced forces, inertia, friction, momentum, Newton's three laws of motion, conservation of momentum, thrust, and pressure. These ideas connect everyda
Key Concepts
Force is a push or pull
Force is a push or pull acting on an object. It can move an object from rest, change speed, change direction, or change shape.
Balanced forces are equal and opposite
Balanced forces are equal and opposite forces that do not change the state of rest or motion, though they can change shape. Unbalanced forces do chang
Inertia is the tendency of
Inertia is the tendency of an object to stay at rest or keep moving with the same velocity.
Mass is a measure of inertia
Mass is a measure of inertia. Massive objects resist changes in motion more than lighter ones.
A body continues in its state
A body continues in its state of rest or uniform motion in a straight line unless acted upon by an unbalanced force. This is also called the law of in
