Front

What causes the tides on Earth?

Back

The gravitational pull of the Moon and the Sun.

Front

What happens to potential energy and kinetic energy as a roller coaster descends from a high point?

Back

Potential energy decreases, and kinetic energy increases.

Front

According to Newton's Third Law of Motion, when you push on a wall, what does the wall do?

Back

The wall pushes back on you with the same force in the opposite direction.

Front

Which of the following elements is a noble gas?

Back

Argon.

Front

What is the relationship between force, mass, and acceleration according to Newton's Second Law of Motion?

Back

Force = Mass × Acceleration.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the formula for calculating gravitational force?

Back

Gravitational Force = (G × m1 × m2) / r², where G is the gravitational constant.

Front

What is the definition of a noble gas?

Back

Noble gases are a group of chemical elements that are odorless, colorless, monatomic gases with very low chemical reactivity.
