Newton's
Question | Answer |
---|---|
gravity | The force that attracts a body toward the center of the earth, or toward any other physical body having mass |
air | The invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen. |
resistance | The refusal to accept or comply with something; the attempt to prevent something by action or argument. |
motion | The action or process of moving or being moved |
action | The fact or process of doing something, typically to achieve an aim |
reaction | An action performed or a feeling experienced in response to a situation or event |
free fall | Downward movement under the force of gravity only: "the path of a body in free fall". |
orbit | The curved path of a celestial object or spacecraft around a star, planet, or moon, esp. a periodic elliptical revolution. |
rolling friction | Rolling resistance, sometimes called rolling friction or rolling drag, is the resistance that occurs when a round object such as a ball. |
Newtons 1st law | first law of motion: a body remains at rest or in motion with a constant velocity unless acted upon by an external force. |
Newtons 2nd law | second law of motion: the rate of change of momentum is proportional to the imposed force and goes in the direction of the force. |
Newtons 3rd law | third law of motion: action and reaction are equal and opposite. |
