Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its velocity.

Front

What is the principle of action and reaction?

Back

The principle states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is a nonmetal?

Back

A nonmetal is an element that is usually brittle, not a good conductor of heat and electricity, and can be found in various states at room temperature.

Front

What is the role of the Moon in Earth's tides?

Back

The Moon has a greater effect on Earth's tides than the Sun due to its proximity to Earth.

Front

What does it mean for an object to be at rest?

Back

An object is at rest when it is not moving and its position does not change over time.

Front

What is the definition of a metal?

Back

A metal is a good conductor of heat and electricity, usually malleable and ductile, and has a shiny appearance.

Front

What is the significance of the position of an object in motion?

Back

The position of an object in motion can determine its potential and kinetic energy at different points.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to most substances when they are heated?

Back

Most substances expand when heated and contract when cooled.

Front

What is the definition of a revolution in physics?

Back

A revolution refers to a complete turn or rotation of an object around a point or axis.
