Energy
 

Energy problem 51


Which of the following statements about cars are correct? Correct the wrong statements.

  • If two cars have the same mass and the same speed, they will have the same kinetic energy.

  • The car with a higher mass certainly has higher kinetic energy.

  • If a car drives straight uniformly, its kinetic energy cannot change in any way.

  • When the speed of a car increases while driving at a constant mass, its kinetic energy will also increase.

  • If two cars have the same kinetic energy and the first has a higher mass than the second, then the second has a lower speed than the first.

  • The following applies to two cars moving straight at the same speed: A car with twice the mass has twice the kinetic energy.

  • The following applies to two cars with the same mass moving straight: The car with twice the speed has twice the kinetic energy.
