# Newton's Laws Vocab

### Newton's Laws of Motion Vocab. Study these for the test!

Centripetal Force in circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve
Circular Motion any motion in which an object is moving along a curved path
Unbalanced Forces forces acting on an object that combine and form a net force that is not zero
Balanced Forces forces acting on an object that combine and form a net force that is zero
Newton's Second Law (Equation) Force = Mass x Acceleration
Inertia the tendency of an object to resist a change in its motion
Net Force the combination of all the forces acting on an object
Newton's First Law An object at rest will stay at rest and an object in motion will stay in motion at the same speed and direction unless an unbalanced force acts upon it
Newton's Third Law For every force (action), there is an equal but opposite force (reaction)
Momentum measure of how hard it is to stop a moving object
Force Pair the forces two objects apply to each other. action and reaction
Momentum Equation P = M x V
Mass Amount of matter in an object
Weight The gravitational force exerted on an object
Gravity An attractive force that exists between all objects that have mass.... What makes objects fall to the ground?
Contact force A push or a pull on an object by another that is touching it
Noncontact force A force that one object can apply to another object without touching it
Force A push or a pull on an object
Friction A force that resists the motion of two surfaces that are touching
Motion An objects change in position
