formula for speed:velocity:acceleration:momentum:average speed
speed= distance/time. velocity= a speed in a given direction. Acceleration= final velocity- initial velocity/time. Momentum= mass x velocity. average speed= total distance/total time.
what is the rate that all objects fall at?
9.8 meter per second 2 until they reach terminal velocity'
wha happens when there is a rough surface>?
greater friction. the greater the force, the more friction you have.
what is the law of universal gravitational force?
part 1: gravitatiol forces increase as mass increase, part2: gravitational forces decrease as distance increases.
the rate at which velocity changes, an object accelerates if its sped changes.direction,or both. the more mass the more acceleration
a measure of gravitational force exerted on an object, the force of gravity pulling you down is the earth
