Question

Identify which is greater at each marked location. Kinetic energy; Potential energy or both

​

Answer 1

Potential energy is the energy when an object is at rest, while the kinetic energy is when the object is in motion.

Formulas

Potential energy is calculated using:

$\mathbf{PE = mgh}$

Where:

• m represents the mass of the object
• g represents acceleration due to gravity (9.8m/s^2)
• h represents the height of the object

While kinetic energy is calculated using:

$\mathbf{KE = \frac 12mv^2}$

Where:

• m represents the mass of the object
• v represents the velocity of the object

Examples

The potential energy of a body that of mass 5 kg at a height of 2.5 meters above the ground is

$\mathbf{PE = 5 \times 9.8 \times 2.5}$

$\mathbf{PE = 122.5J}$

The kinetic energy of a body that of mass 5 kg moving at a velocity of 2.5m/s is

$\mathbf{KE =\frac12 \times 5 \times 2.5^2}$

$\mathbf{KE =16.625J}$
