Front

The distance an object travels per unit of time.

Back

Speed is the measure of how fast an object is moving, calculated as distance divided by time.

Front

What is the net force and direction when two forces of 5 N to the right and 2 N to the left are applied?

Back

The net force is 3 N to the right (5 N - 2 N = 3 N).

Front

A disturbance that transfers energy from place to place.

Back

A wave is a disturbance that moves through a medium, transferring energy without transferring matter.

Front

The material through which a wave travels.

Back

Medium is the substance or material that carries the wave, such as air, water, or solid materials.

Front

A wave that requires a medium through which to travel.

Back

Mechanical wave is a type of wave that cannot travel through a vacuum and needs a medium, like sound waves.

Front

The highest point of a wave.

Back

Crest is the peak point of a wave, representing the maximum displacement of the medium from its rest position.

Front

The lowest point of a wave.

Back

Trough is the lowest point of a wave, representing the minimum displacement of the medium from its rest position.

Front

The distance between two consecutive crests or troughs in a wave.

Back

Wavelength is the measurement of the distance between two successive points in phase on a wave.

Front

The height of a wave from its rest position to the crest or trough.

Back

Amplitude is the maximum extent of a wave's displacement from its rest position, indicating the energy of the wave.

Front

The rate of change of velocity of an object.

Back

Acceleration is the change in velocity per unit of time, indicating how quickly an object is speeding up or slowing down.
