What is studying science for many hours each day.
300
A graph will generally look like this when showing constant speed.
What is a straight increasing or decreasing line.
300

This is the study of energy and its changes.
What is physics.
500
When measuring motion, the frame of reference is this.
What is stationary.

This is the Law of Conservation of Momentum.
What is Law of physics states that the linear momentum does not change unless an external force acts upon it. The law of conservation of momentum explains that momentum is neither lost or gained. "when two bodies collide with one another, the total energy remains constant"
500
This is the common unit for momentum.
