Newton's Laws of Motion Vocab. Study these for the test!
Question | Answer |
---|---|
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 |
