Forces and motion quiz subjects 8th grade
Term | Definition |
---|---|
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 |
