What does the Law of Conservation of Momentum state?

When two objects collide, the total momentum before the collision is the same as the total momentum after the collision


Momentum depends on what two things?

Mass and Velocity


Five km west is an example of?

Displacement


When looking at a speedtime (velocity/acceleration) graph, how do you know if the time intervals are positively accelerating, negatively accelerating, or showing zero acceleration?

Positiveline slopes upward, the steeper the line the faster the acceleration. Negativeline slopes downward. Horizontal line equals zero acceleration

kilogram


What is the equation for calculating momentum?

mass x velocity

Newton


If the forces acting on an object are balanced the net force is?

zero


What are balanced forces?

Forces that cancel each other out and not cause a change in an object's position (motion)


If net force acts on an angle to the direction an object is moving, the object will follow a(n) _______ path?

curved
