two blocks are released from the top of a building. one falls straight down while the other slides down a smooth ramp. if all friction is ignored, which one is moving faster when it reaches the bottom?



Answer :

The first and second blocks move at the same speed.

What is the law of conservation of mechanical energy ?

The law of conservation of mechanical energy states that the total mechanical energy of a system is constant if the only forces acting on the system are conservative.

The total mechanical energy of a system is the sum of kinetic and potential energy.

E = KE + PE

This is the total energy, kinetic energy and potential energy of the system.

The kinetic energy of the

system is:

KE = 1/2 x m x v^{2}

This is the mass and velocity of the object.

The gravitational potential energy is:

PE = mgh

Here is the acceleration of gravity and altitude.
