refer to a situation where you exert a force F on a crate of mass M, moving it at a speed v a distance d across a floor in a time interval t. The quantity F d/t is?
a.)kinetic energy of the crate
b.)potential energy of the crate
c.)linear momentum of the crate
d.)work you do on the crate
e.)power you supply to the crate
Review the definitions of KE, power, momentum etc. Then tell us what you think.
If you just pass off your multiple choice questions for us to do, you won't learn much physics.
The quantity F d/t represents the work you do on the crate. To understand why, let's break down the equation:
F is the force you exert on the crate. This force is responsible for moving the crate.
d is the distance you move the crate over the floor. It represents the displacement of the crate.
t is the time interval it takes for you to move the crate.
The expression F d/t is actually the formula for work done. Work is defined as the force applied on an object multiplied by the displacement of the object in the direction of the force. In this case, the force you exert on the crate is F, and the displacement is d in the direction of the force. So, the quantity F d/t represents the work you do on the crate.
Therefore, the correct answer is d.) work you do on the crate.
