Force | A push or pull on an object. |
Contact Force | Is a push or a pull on one object by another that is touching it. |
Noncontact Force | A force that one object can apply to another object without touching it. |
Gravity | Is an attractive force that exist between all the objects that have mass. |
Mass | Is the amount of matter in an object. |
Weight | Is gravitational force exerted on an object. |
Friction | Is a force that resist the motion of two surface that are touching. |
Net Force | The combination of all the force acting on an object. |
Balanced Force | Forces acting on an object that combine and form a net force of zero. |
Unbalanced Force | Force acting on an object that combine and form a net force that is not zero. |
Newtons's First Law of Motion | If the net force on an object is zero. |
Inertia | The tendency of an object to resist a change in its motion. |
Newton's Second Law of Motion | The acceleration of an object is equal to the net force acting on an object divided by the object's mass. |
Circular Motion | Is any motion in which an object is moving along a curved path |
Centripetal Force | In circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve. |
Newton's Third Law of Motion | When one object exerts a force on a second object, the second exerts equal force in the opposite direction on the first object. |
Momentum | Is the measure of how hard it is to stop a moving object. |
Law of Conservation of Momentum | The total momentum of a group of objects stays the same unless outside forces act on an object. |
