front 1 Motion | back 1 the action or process of moving or being moved. |
front 2 Friction | back 2 the force that resists motion when the surface of one object comes in contact with the surface of another. |
front 3 Static Friction | back 3 a force that keeps an object at rest. |
front 4 Kinetic Friction | back 4 a force that acts between moving surfaces. |
front 5 Liquid Friction | back 5 the force that resists motion either within the fluid itself or of another medium moving through the fluid. |
front 6 Acceleration | back 6 increase in the rate or speed of something. |
front 7 Newtons First Law of Motion | back 7 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. |
front 8 Newtons Second Law of Motion | back 8 the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. |
front 9 Newtons Third Law of Motion | back 9 for every action in nature there is an equal and opposite reaction. |
front 10 Gravity | back 10 the force that attracts a body toward the center of the earth, or toward any other physical body having mass. |
front 11 Pressure | back 11 continuous physical force exerted on or against an object by something in contact with it. |
front 12 Buoyancy | back 12 the ability or tendency to float in water or air or some other fluid. |
