Question

Greg and Shawn are studying for a physical science test. Greg thinks that the kinetic energy of an object depends on the height and speed of and object , but Shawn thinks it depends on the bass of and object. Who is right and why
A.neither is completely right. Shawn is partly correct since kinetic energy depends on mass , but Greg is also partly right since it also depends on speed.

B. Both Greg and Shawn are correct since kinetic energy depends on mass, height and speed of an object.

C. Greg is right. Increasing the height or speed of an object increases the kinetic energy of an object.

D. Shawn is right. The mass of an object determines the intertia of the object. Increasing inertia is the only thing that will increase kinetic energy..

Answer 1

Kinetic energy of any object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.The kinetic energy of any moving object depends upon  its mass and speed.

Hence, option A is correct.

A.neither is completely right. Shawn is partly correct since kinetic energy depends on mass , but Greg is also partly right since it also depends on speed.
