Kinetic Energy Graph

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

• It is halved

• It doubles

• It triples

• It quadruples

Based on the graph, when the mass doubles from 500 kg to 1000 kg, what happens to kinetic energy?

• Kinetic energy remains the same

• Kinetic energy doubles

• Kinetic energy quadruples

• There is too little information to know

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

• YES

• NO

This graph is based on a rolling object with a mass of 2000 kg. At a speed of 80 m/s, the object has 1,000,000 J of kinetic energy. How much kinetic energy does it have when the speed doubles?

• 1,000,000 J

• 2,000,000 J

• 3,000,000 J

• 4,000,000 J
