Question

Please help- Determine the relationship between potential and kinetic energy in a system.

Answer 1

Answer:

See the explanation below.

Explanation:

At the highest point is where potential energy is maximum and kinetic energy is zero.

Because potential energy is defined as the product of mass by gravitational acceleration by height, this is expressed within the following equation:

$E_{pot}=m*g*h$

where:

Epot = potential energy [J]

m = mass [kg]

g = gravity acceleration [m/s²]

h = elevation [m]

As we can see, if the body is located at the highest point with respect to the ground, potential energy has the maximum value. Meanwhile, the kinetic energy is zero because there is no movement.

At the lowest point is where the kinetic energy is maximum and the potential energy es zero.

When the body is in the lowest location, the height is zero, therefore potential energy is zero (h = 0). But the body is moving with a certain velocity that is we have kinetic energy.
