|
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 speed-time (velocity/acceleration) graph, how do you know if the time intervals are positively accelerating, negatively accelerating, or showing zero acceleration?
|
Positive-line slopes upward, the steeper the line the faster the acceleration. Negative-line slopes downward. Horizontal line equals zero acceleration
|

|
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)
|
|
|

|
curved
|
|
|
The gravitational force of any object near Earth's surface is measured at what acceleration?
|
9.8 m/s2
|
|
|
What force exists between any two objects with mass? This also keeps up from floating away into space
