forces in motion
Question | Answer |
---|---|
Gravity | a fundamental physical force that is responsible for interactions which occur because of mass between particles, between aggregations of matter (such as stars and planets), and between particles (such as photons) and aggregations of matter, that is 10-39 |
Mass | is a measurement of the amount of matter something contains. |
weight | The amount that a thing weighs |
Push | to press against with force in order to drive or impel |
pull | to exert force upon so as to cause or tend to cause motion toward the force |
Friction | the rubbing of one body against another |
Force | strength or energy exerted or brought to bear |
motion | an act, process, or instance of changing place |
velocity | : quickness of motion : SPEED |
Inertia | the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. |
Speed | the rate at which someone or something moves or travels. |
Position | the place where someone or something is in relation to other people or things. |
Axis | the imaginary straight line that something (such as the Earth) turns around. |
Unbalanced Force | are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving |
Acceleration | the rate at which the speed of a moving object changes over time |
Direction | the rate at which the speed of a moving object changes over time |
Air resistance | Air resistance is defined as the force that acts in the opposite direction to an object moving through the air |
Momentum | a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity |
Resist | to exert force in opposition |
Deceleration | to reduce the speed of |
Newton’s First Law | every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. |
Newton’s Second Law | force is equal to mass times acceleration |
Newton’s Third Law | for every action there is an equal and opposite reaction |
