What is the definition of net work done in physics?

Back

Net work done is the total work done on an object, taking into account both positive and negative work. It is defined as the product of the net force acting on the object and the distance moved in the direction of the force.

Front

In which scenario is no net work done?

Back

When an object moves at a constant speed on a flat road, no net work is done because the forces acting on it are balanced.

Front

What does the electromagnetic spectrum represent?

Back

The electromagnetic spectrum represents the range of all types of electromagnetic radiation, including visible light, radio waves, X-rays, and more.

Front

What is the relationship between pitch and sound wave frequency?

Back

The pitch of a sound corresponds to the frequency of the sound wave; higher frequencies result in higher pitches.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement of the medium from its rest position.

Front

What happens when a switch is open in an electrical circuit?

Back

When a switch is open, the circuit is broken, and electric charges cannot flow, preventing the circuit from functioning.

Front

What is the definition of frequency in the context of waves?

Back

Frequency is the number of complete cycles of a wave that pass a given point in one second, measured in hertz (Hz).

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to produce a wave of lesser amplitude, often resulting in cancellation.

Front

What is the formula for calculating work done?

Back

Work done (W) is calculated using the formula W = F × d × cos(θ), where F is the force applied, d is the distance moved, and θ is the angle between the force and the direction of motion.

Front

What is the definition of amplitude in wave physics?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.
