rate of change in distance with respect to time
law of intertia
other name for 1st law
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
change in displacement or direction with respect to time
change in velocity over time
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
friction produced by the atmosphere
3rd law of action-reaction
for every action there is an equal and opposite reaction
when two surfaces slide past each other
makes a tire turn and a ball roll
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
force that exists between any two objects that are touching
