What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect kinetic energy?

Back

As mass increases, kinetic energy increases if the speed remains constant. This is because kinetic energy is directly proportional to mass.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of speed. If speed doubles, kinetic energy increases by a factor of four, assuming mass remains constant.

Front

What is the distance from Earth to the Sun?

Back

The average distance from Earth to the Sun is about 93 million miles (150 million kilometers).

Front

What is the distance from Earth to the Moon?

Back

The average distance from Earth to the Moon is about 238,855 miles (384,400 kilometers).

Front

What is the distance across our solar system?

Back

The distance across our solar system varies, but it is often considered to be about 1.5 billion miles (2.4 billion kilometers) to the edge of the Kuiper Belt.

Front

What is the distance across the Milky Way galaxy?

Back

The Milky Way galaxy is about 100,000 light-years in diameter.

Front

What is the order of distances from Earth to various celestial bodies?

Back

The order from longest to shortest distance is: Distance across the Milky Way galaxy, Distance across our solar system, Distance from Earth to the Sun, Distance from Earth to the Moon.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
