• Kinetic Energy

Calculate the kinetic energy of an object of mass 2 kg moving with a speed of 3 m/s

• 9 J

• 1 J

• 3 J

• 10 J

What is the speed of an object of 1 kg mass with a kinetic energy of 50 J?

• 10 m/s

• 20 m/s

• 50 m/s

• 25 m/s

When is potential energy transformed into kinetic energy?

• When an object at rest is lifted to a higher elevation.

• When an object at rest remains at rest.

• When an object at rest is put into motion.

• When an object in motion is stopped and put at rest.

Find the gravitational potential energy of 2.5 kg mass kept at a height of 15 m above the ground.

• 367.5 J

• 368.5 J

• 370.5 J

• 371.5 J
