Work and Energy Flashcard

Front

What does the law of conservation of momentum state?

Back

The momentum of any closed, isolated system does not change.

Front

What is the formula to calculate work done when a force is applied over a distance?

Back

Work done = Force × Distance

Front

What does the equation FΔt = pf − pi represent?

Back

Impulse-momentum theorem

Front

What is the term for energy stored in an object when it is stretched or compressed?

Back

Elastic potential energy

Front

What type of energy is converted to kinetic energy in a rocket when its engines are fired?

Back

Chemical energy

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the unit of work in the International System of Units (SI)?

Back

Joule (J)

Front

Explain the concept of kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv².

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.
