Review Q #2

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is gravitational potential energy (GPE)?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

How does mass affect gravitational potential energy?

Back

The gravitational potential energy increases with the mass of the object and its height above the ground.

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

At what point does an object have the most gravitational potential energy when thrown into the air?

Back

An object has the most gravitational potential energy at its highest point.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

How do potential and kinetic energy relate to each other?

Back

As potential energy decreases, kinetic energy increases, and vice versa, in a closed system.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy is GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the role of gravity in potential energy?

Back

Gravity is the force that gives an object its potential energy based on its height above the ground.
