speed

rate of change in distance with respect to time

s=d/t

speed equation

law of intertia

other name for 1st law

intertia

when an object is at rest it stays at rest and when an object in motion it stays in motion unless acted upon by an unbalanced force

velocity

change in displacement or direction with respect to time

acceleration

change in velocity over time

a=(vf-vi)/t

acceleration equation

2nd law of force and acceleration

amount of force needed to make an object change its speed depends on the mass of the object and the acceleration required

1st law of motion

object at rest stays at rest and an object in motion at a constant speed stays in motion unless acted upon by an unbalanced force

air resistance

friction produced by the atmosphere

3rd law of action-reaction

for every action there is an equal and opposite reaction

sliding friction

when two surfaces slide past each other

rolling friction

makes a tire turn and a ball roll

static friction

hinders a stationary object from moving on a surface when a force is applied to that object

need for speed difference in angles

bigger angle went faster

pick me up difference in angles

speed/acceleration increased with angle

f=ma

equation for force

friction

force that exists between any two objects that are touching
