Physical Science Midterm Test Review

Front

What is wavelength?

Back

Wavelength is the distance between successive crests (or troughs) of a wave, typically measured in meters.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, which relates to the energy and volume of the wave.

Front

How does frequency relate to sound?

Back

Frequency is the number of waves that pass a point in one second, determining the pitch of the sound.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface tilted at an angle to help lift heavy objects with less force.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an electric generator?

Back

An electric generator is a device that converts mechanical energy into electrical energy, typically using electromagnetic induction.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, affecting its speed and direction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as 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, such as gravitational potential energy.
