What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is the mass in kilograms and v is the velocity in meters per second.

Front

What is the unit of momentum?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is the mass in kilograms and v is the velocity in meters per second.

Front

What is the unit of kinetic energy?

Back

The unit of kinetic energy is Joules (J).

Front

What happens to kinetic energy when velocity is doubled?

Back

When the velocity of an object is doubled, its kinetic energy quadruples.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, commonly gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, at the highest point, kinetic energy is zero and potential energy is at its maximum.

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.
