A push or pull
the speed of an object in a particular direction
speeding up, slowing down, turning
distance traveled per unit time
Total of all traveling
distance and direction of an object's change in position from the starting point
1st Law of Motion
An object in motion stays in motion until a force makes it stop. An object at rest stays at rest until a force makes it move
2nd Law of Motion
A net force acting on an object causes the change to accelerate in the direction of the force. (Force=massxaccelaration)
3rd Law of Motion
for every action there is an equal and opposite reaction. Ex.- Bumper cars, frogs on a lily pad
equal forces acting on an object in opposite directions. No movement.
forces that produce a nonzero net force, which changes an object's motion.
the sum of the forces on an object when unbalanced forces are applied to it.
