Distance and Displacement
On a football field, Albert Einstein walks from the 20 yd line to the next 40 yd line, and then back to the 30 yd. What distance has he traveled?
30 yards
What is the difference between speed and velocity?
Velocity includes direction (it's a vector)
What is the formula for momentum?
p=mv
What is the formula for acceleration?
acceleration = (final velocity - initial velocity) / time

What is the formula for velocity?
d/t = v (distance divided by time)
