Front

What is the equation for calculating an object's gravitational potential energy?

Back

PE = mgh, where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height.

Front

In which direction does heat flow spontaneously?

Back

Heat flows spontaneously from HOT objects to COLD objects.

Front

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

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

Which type of wave has the most energy: Sound, UV, Gamma, or X-ray?

Back

Gamma waves have the most energy.

Front

Why does a metal spoon feel colder than a wooden spoon at room temperature?

Back

The metal spoon feels colder because it is a better conductor and transfers thermal energy rapidly away from your skin.

Front

What is the definition of displacement in physics?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the engineering design process?

Back

The engineering design process is a series of steps that engineers follow to come up with a solution to a problem.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from the starting point to the endpoint.

Front

What is thermal conductivity?

Back

Thermal conductivity is a measure of a material's ability to conduct heat.

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.
