What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is often associated with gravitational energy, where it depends on the height of the object above a reference point.

How is power defined in physics?

Back

Power is defined as the rate at which work is done or energy is transferred over time. It can be calculated using the formula: Power = Work/Time.

What is the formula for gravitational potential energy?

Front

What does a speed versus time graph represent?

Back

A speed versus time graph shows how the speed of an object changes over time. The area under the graph represents the distance traveled.

Front

What is the principle of conservation of mechanical energy?

Back

The principle of conservation of mechanical energy states that in the absence of non-conservative forces (like friction), the total mechanical energy (kinetic + potential) of an object remains constant.

What is kinetic energy?

Front

What is the relationship between speed and distance in a speed versus time graph?

Back

In a speed versus time graph, the distance covered is equal to the area under the graph. A larger area indicates greater distance.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, keeping the total mechanical energy constant (in the absence of air resistance).
