Newton's 1st Law | without force, a body at rest, stays at rest, a moving body continues moving without force to stop it |
Newton's 2nd Law | Force causes objects to accelerate |
Newton's 2nd Law | Acceleration = force/mass |
Newton's 2nd Law | It takes more strength to push a car than it does to push a bicycle |
Newton's 3rd Law | All forces result from interactions between pairs of objects |
Newton's 3rd Law | For every action there is an equal and opposite reaction |
Gravity | Force of attraction or pull between objects |
Conduction | Transfer process where internal energy is transferred because of differences in temperatur |
Radiation | Transfer of energy from the sun to the Earth |
Convection | Internal energy moves from place to place as the matter that contains it moves from place to place |
Refraction | Bending of light as it passes through differing densities |
Diffraction | Ability of waves to bend around corners and spread whenever they encouter obstacles: peering through slightly closed eyes, images appear blurred |
