Physics PE, KE and Momentum

Front

What is the definition of Potential Energy (PE)?

Back

Potential Energy (PE) is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

What is the definition of Kinetic Energy (KE)?

Back

Kinetic Energy (KE) is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to PE and KE in a pendulum as it swings from its highest point to its lowest point?

Back

As a pendulum swings from its highest point to its lowest point, Potential Energy (PE) decreases while Kinetic Energy (KE) increases.

Front

What is the formula for calculating momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

How does mass affect momentum if velocity is constant?

Back

If velocity is constant, an increase in mass will result in an increase in momentum.

Front

What is the relationship between maximum kinetic energy and maximum potential energy in a mass-spring system?

Back

In a mass-spring system, maximum kinetic energy and maximum potential energy are equal but occur at different positions in the oscillation.

Front

What is the significance of the equilibrium position in a mass-spring system?

Back

The equilibrium position is where the net force on the mass is zero, and it is the point where potential energy is minimum and kinetic energy is maximum.

Front

What is the effect of height on potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has due to gravitational force.
