APS Final - Motion, Forces, Mechanical Energy Unit

What happens to an object speed when it is turning?

speed stays the same

What does a steeper slope on a position time graph mean?

means object is moving faster

what happens to an objects velocity change when turning?

velocity changes, increase or decrease

what happens to an objects acceleration when turning

acceleration changes due to velocity

why is acceleration the same for objects in free fall

because the f/m ratio is the same for all objects

what is equilibrium

at rest or moving with constant velocity, accel=0, net force=0

what is net force

total amount of force acting on an object

what does constant velocity mean

no change in speed or direction

An object is fast with more mass in (KE or PE)

KE

An object has more mass, strong grav. field, and his higher up in (PE or KE)

PE

In what circumstances would PE and KE have equal amounts

halfway through free fall, halfway down ramp

when is energy conserved in a system

no air resistance, no friction
