Force & Motion
Question | Answer |
---|---|
Friction | A force that opposes the motion of another object; making the object slow down, or giving it traction to get moving. |
Gravity | The force that pulls every object towards one another. |
Mass | The measure of the amount of matter (stuff) in an object. |
Acceleration / Force | The more force you apply, the greater the acceleration. The less force you apply, the lesser the acceleration |
Acceleration / Mass | The greater the mass, the more force necessary to get an object to accelerate. |
Weight | A gravitational force exerted on an object's mass, that changes with position. |
Speed | Distance over time. |
Velocity | Speed in a given direction. |
Acceleration | Change in speed or direction. |
Balanced Forces | When the two forces acting on a singular object are equal. There is no movement. |
Unbalanced Forces | When the two forces acting on a singular object are not equal. There is movement in the direction that the stronger force is pushing/pulling |
Inertia | The resistance to change in motion. |
Force | A push or a pull in any direct |
Newton | The unit that force is measured in. |
Net Force | The combination of all the forces acting on an object |
Newton's 1st Law | An object in motion stays in motion & an object at rest stays at rest unless acted upon by an unbalanced force. |
Newton's 2nd Law | Force = mass x acceleration |
Newton's 3rd Law | For every action there is an equal and opposite reaction |
