Rocket Sled Unit Review: Motion and Forces

Front

What two factors determine a moving cart's kinetic energy?

Back

Cart mass and cart speed together determine energy.

Front

What happens when one go-kart has greater thrust than another?

Back

The go-kart with greater thrust accelerates faster down the track.

Front

How does the motion of a car compare to a truck if the car shows a greater rate of negative acceleration?

Back

The car is showing a greater rate of negative acceleration than the truck.

Front

If the speed of a moving object doubles, what happens to its kinetic energy?

Back

It becomes four times as large.

Front

How does force affect a change in motion for any object?

Back

A larger force causes a larger change in motion.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the relationship between force and acceleration according to Newton's second law?

Back

Force equals mass times acceleration (F = m * a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
