Mini-Quiz: Derivation of Velocity-Time Gravity Equations

by Ron Kurtus (revised 7 January 2011)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What does dv/dt stand for?

It is d times v divided by d times t

It has no real meaning

It is a small change in velocity divided by an increment in time

2. Why is g*dt integrated over the time interval 0 to t?

You are starting from zero time to some arbitrary time

The initial velocity is 0

Because g can vary between 0 and t

3. How is the equation for time with respect to a given velocity determined?

Integrate the velocity equation over time

Take the velocity for a given time equation and solve for t

There is no equation for time with respect to a given velocity

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Use your time wisely
