Back

Newtons

Front

What is defined as a PUSH or PULL of an object?

Back

Force

Front

What is the equation for calculating an object's gravitational potential energy?

Back

PE = mgh

Front

At which point is potential energy greatest in a system?

Back

At the highest point (W) in the system.

Front

Back

Balanced force.

Front

What is the definition of gravitational potential energy?

Back

The energy an object possesses due to its position in a gravitational field.

Front

What does the symbol 'm' represent in the equation PE = mgh?

Back

Mass of the object.

Front

What does 'g' represent in the equation PE = mgh?

Back

Acceleration due to gravity (approximately 9.81 m/s² on Earth).

Front

What does 'h' represent in the equation PE = mgh?

Back

Height of the object above a reference point.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause a change in motion.
