Suppose the initial kinetic energy and final potential energy in an experiment are both zero. what can you conc ude?

The object started from rest and travelled downward

Explanation:

The kinetic energy of an object is given by:

where m is the mass of the object and v its speed. The problem tells us that the initial kinetic energy is zero, so the initial speed must be zero: v=0.

The potential energy of an object is given by:

where g is the acceleration due to gravity and h is the height of the object above the groun. Since the final potential energy is zero, the final height must be zero: h=0.

The total mechanical energy of the object, which is sum of the kinetic and potential energy, must be conserved:

Initially, there is no kinetic energy, so the mechanical energy is just potential energy: this means that the object is located at a certain height above the ground, and it is at rest.

At the end, there is no potential energy, so the mechanical energy is just kinetic energy: this means that the object reached the ground, and it has a certain speed.

Therefore, we can conclude that the object travelled downward.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
