Unit 8.1 Flashcard 6

Front

What is kinetic energy?

Back

Kinetic energy is the energy of objects in motion.

Front

What two properties of an object affect its kinetic energy?

Back

Mass and speed.

Front

Which graph shows the relationship between kinetic energy and speed?

Back

Graph B.

Front

What happens to the kinetic energy of an object when its speed is doubled?

Back

The kinetic energy quadruples.

Front

What has a larger impact on the kinetic energy of an object and the damage in a collision?

Back

Speed.

Front

Define kinetic energy in terms of motion.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * speed (v)^2.

Front

How does mass affect kinetic energy?

Back

Increasing the mass of an object increases its kinetic energy if speed remains constant.

Front

How does speed affect kinetic energy?

Back

Increasing the speed of an object increases its kinetic energy exponentially.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is proportional to the square of the speed.
