  2. Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity and the same acceleration.

    When a force acts on an object, it often makes itmove faster or in a different direction. Once something is moving,you don't need a force to keep it moving: it will carry on moving allby itself unless another force stops it. When a rocketblasts intospace, you need a force to make it lift off to begin with and toovercome the force of Earth's gravity...

    It takes a force to make something move in adifferent way, and that includes changing the direction in whichsomething is moving even if its speed stays the same. If you want tomake something go round in a circle, you have to apply a force tomake it turn and keep on applying that force to keep it turning. Thatmakes sense: something moving in a circl...

    Forces make things move—but they also bringmoving things to a halt. Roll a toy car over a rug and it'll quicklycome to a standstill. The force of frictionsteals the car'senergy and slows it down. Friction is the force between two differentobjects that are in contact, either when they're locked together andtouching or when one of them slides past th...

    Have you ever tried tugging the aluminum ring-pull of adrinks can and found it suddenly snaps off in your hand? What you'retrying to do is use a force to make the ring-pull move and changedirection at the same time. But instead of doing what you expect, onepart of the ring-pull snaps away from the other. This is an exampleof how forces can change a...

  4. Motion is the area of physics that studies how things move. It was developed about 300 years ago by Isaac Newton. He discovered that all objects move according to three basic laws. Newton’s Laws can explain almost all of physics. When we look at the other branches of classical physics, they all can be explained…

  5. Motion is the action of changing location or position. The general study of the relationships between motion, forces, and energy is called mechanics.
