Question

how does kinetic energy of an object change if a) its mass is doubled, and b) its speed is doubled ​

Answer 1

Explanation:

K = 1/2 mv^2

a. kinetic energy is doubled if mass is doubled.

b. Kinetic energy becomes four times the initial value if speed is doubled.

Answer 2

Answer:

HERE IS YOUR ANSWER

Explanation:

If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word "kinetic" comes from the Greek word "kinesis" which means motion. Kinetic energy can be passed from one object to another in the form of a collision.
