Physics Review (Collisions, Momentum, Energy, Work, Power, Heat, and Waves)

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (p) is p = m * v, where m is mass and v is velocity.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic energy, potential energy, thermal energy, etc.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. For example, gravitational potential energy depends on an object's height.

Front

What is work in physics?

Back

Work is done when a force causes an object to move. It is calculated using the formula W = F * d, where F is force and d is distance.

Front

What is power?

Back

Power is the rate at which work is done or energy is transferred. It is calculated using the formula P = W/t, where W is work and t is time.

Front

What is heat?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is the Doppler Effect?

Back

The Doppler Effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force.
