IPC - Physics Semester Exam Review

Front

What is a renewable energy resource?

Back

A renewable energy resource is a natural resource that can be replenished naturally over time, such as solar energy from the sun.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave, opposite to the crest.

Front

How do you calculate the speed of a wave?

Back

Speed of a wave (v) can be calculated using the formula: v = frequency (f) × wavelength (λ).

Front

If a wave has a frequency of 50 Hz and a wavelength of 10 m, what is its speed?

Back

The speed of the wave is 500 m/s.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 0.5 × mass (m) × velocity (v)².

Front

If an object creates 33,750J of energy traveling at 30m/s, what is its mass?

Back

The mass of the object is 75 kg.

Front

How do you calculate distance traveled?

Back

Distance can be calculated using the formula: Distance = Speed × Time.

Front

If a car travels at 30 miles/hr for 3 hours, how far does it travel?

Back

The car travels 90 miles.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave, opposite to the trough.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
