Front

How does gravitational force change as two objects move farther apart?

Back

The gravitational force decreases as two objects move farther apart.

Front

Which of the following describes the structure of a solid?

Back

In a solid, particles vibrate in place.

Front

Which technology depends on the ability of waves to carry energy?

Back

Radio signals moving through the atmosphere depend on the ability of waves to carry energy.

Front

What does Newton's second law state about force and acceleration?

Back

A larger force produces a larger acceleration.

Front

What happens to the spoon when hot coffee is stirred?

Back

Heat energy is transferred from the coffee to the spoon.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.

Front

What is the structure of liquids compared to solids?

Back

In liquids, particles are close together but can move around, unlike solids where particles vibrate in place.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration.

Front

What is thermal energy transfer?

Back

Thermal energy transfer is the movement of heat from one object to another.

Front

What is the definition of waves in physics?

Back

Waves are disturbances that transfer energy from one place to another.
