Force and Motion Unit Vocabulary Mass The amount of matter that makes up an object. – Force A push or pull. – Inertia Means that an object in motion will stay in motion in the – same direction and an object at rest will stay at rest, unless another force acts upon it. Gravity A force that pulls objects toward each other. – Air Resistance The force of friction that acts between a moving – object and air particles. Friction A force that acts between surfaces that touch each other. – Motion A change in an – object’s position. Position The location of an object. – Distance The length of a line between 2 points. – Direction The path that a moving object follows. – Speed A measure of how far an object moves in a certain amount – of time. Velocity An speed and direction. – object’s Distance-Time Graph A line graph that shows an motion, – object’s with time on the x-axis and distance on the y-axis.
