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

Front

What is a node in a wave?

Back

A point in a standing wave where the wave has minimum amplitude.

Front

How is power calculated in physics?

Back

Power is calculated as work done divided by time taken (P = W/t).

Front

What is conduction in terms of heat transfer?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is a transverse wave?

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave.

Front

What is mechanical energy?

Back

The sum of potential energy and kinetic energy in an object.

Front

How do you calculate the potential energy of an object?

Back

Potential energy (PE) is calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the formula for calculating work done?

Back

Work done (W) is calculated as W = Fd, where F is force and d is distance.

Front

What is the definition of momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is a wave's wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest.
