more

Front

What is the acceleration due to the force of gravity here on Earth? (in meters per second squared)

Back

9.8 m/s²

Front

At which point is potential energy greatest? (Choose from W, X, Y, Z)

Back

W

Front

Which has more momentum: a car at a stop light or a bike moving at 15 mph?

Back

bike

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is momentum?

Back

The quantity of motion an object has, calculated as the product of its mass and velocity.

Front

What is the formula for momentum?

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.
