# Forces and Motion 8

### Forces and motion quiz subjects 8th grade

TermDefinition
Mass -The amount of Matter or "stuff" in an object -measured in grams (g) or kilograms (kg) unaffected bye gravity
weight The gravitational attraction of two objects (usually measuring the attraction between the object and it's home planet - measured in newton's (N)
unbalanced force When the forces acting on an object are not equal causing a change in motion
balanced force When the net force of an object is equal from all directions (0N) and the object stays in one place
Equation to calculate time t= d/v
Equation to calculate distance d= t*V
equation to calculate speed v= d/t
speed How fast an object is going (how far it travels in X amount of time)
distance How far an object travels
Velocity Speed with a direction attached to it
Net force The overall (All of) the force acting on an object
