... Work is defined as the force on an object in the direction of an object’s motion multiplied by the idstance the object moves. Or: W=(F)(d). If the force is at an angle to the object’s motion, only the component of the force that is parallel to the object’s motion is used to determine the work on the ...

Newton`s Laws Vocabulary
... Gravity – the force of attraction that moves bodies towards the center of the earth. Inertia – the tendency of a body to preserve its state of rest or motion unless acted upon by an external force. Newton (N) – the unit for the amount of force an object contains. Traction – a kind of friction that a ...
