2

Use this equation when given acceleration, displacement, and initial velocity. 

v2=v02+2ax

2

This quantity can be found by calculating the slope of a velocity-time graph.

What is acceleration?

2

"Every object retains its state of rest or state of uniform straight-line motion unless acted on by an unbalanced force"

Newton's First Law or Law of Inertia

2

All objects with mass experience this attractive force.

What is gravity?

3

This state of motion is characterized by zero acceleration and constant, non zero velocity.

What is dynamic equilibrium? 

3

This equation is used to calculate the force of attraction between two objects with mass.

What is Newton's Law of Universal Gravitation or 

Fg=G(m1m2)/r2
