Mass, Speed, and Kinetic Energy

Front

What two things determine the amount of energy an object has?

Back

Mass and speed.

Front

Can a kinetic energy vs mass graph show a curved line?

Back

No.

Front

How much less kinetic energy does an object have if it changes speed from 100 km/h to 50 km/h?

Back

Kinetic energy decreases from 400 kJ to 100 kJ.

Front

Based on the kinetic energy vs mass graph, when the mass of an object doubles, what happens to kinetic energy?

Back

It doubles.

Front

Can a kinetic energy vs speed graph show a curved line?

Back

Yes.

Front

What is the formula for kinetic energy?

Back

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

Front

If an object's mass is tripled, how does its kinetic energy change if speed remains constant?

Back

Kinetic energy triples.

Front

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

Back

Kinetic energy increases by a factor of four.

Front

Define kinetic energy in your own words.

Back

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

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass.
