24-25 1st Semester Final Review

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate or change its motion. They are not equal in size and opposite in direction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. For example, a moving car has kinetic energy.

Front

What is a revolution in terms of Earth's movement?

Back

A revolution is the movement of the Earth around the Sun, taking approximately 365.25 days to complete one full orbit.

Front

What type of energy does a moving car possess?

Back

A moving car possesses kinetic energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a book on a shelf has potential energy.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

Can you give an example of potential energy?

Back

An example of potential energy is a stretched rubber band or a rock at the top of a hill.

Front

What happens to an object when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

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 is the role of gravity in potential energy?

Back

Gravity affects potential energy by determining how much energy an object has based on its height above the ground.
