Physical Science Review

Front

What helps slow a box as it slides down a ramp?

Back

Friction is the force that opposes the motion of the box, helping to slow it down.

Front

True or False: The greater the energy of an electromagnetic wave, the higher its frequency and the shorter its wavelength.

Back

True. Higher energy waves have higher frequencies and shorter wavelengths.

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases. This is because frequency and wavelength are inversely related.

Front

What does the Law of Conservation of Matter state?

Back

Matter cannot be created or destroyed; it can only change forms.

Front

What type of energy does a rock at the edge of a cliff possess?

Back

Potential energy, due to its position and the gravitational force acting on it.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion, calculated as 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 based on its position or state.

Front

What is the relationship between frequency and wavelength in waves?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
