Science Notes for Systems in Action

Force of gravity = __________.

mass (kg) x gravity (9.8)

What is the formula for force?

Force = mass x acceleration.

What is Newton's second law of motion?

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

What does gravitational force depend on?

Gravitational force depends on the masses of the objects and the distance between them.

How do you calculate weight?

Weight = mass x gravitational acceleration (9.8 m/s²).

What is inertia?

Inertia is the resistance of an object to change its state of motion.

What is the law of universal gravitation?

Every point mass attracts every other point mass with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.

What happens to weight on the moon?

Weight is less on the moon due to its lower gravitational force compared to Earth.

What is mass?

Mass is the amount of matter in an object, typically measured in kilograms.

What is kinetic energy?

Kinetic energy is the energy an object possesses due to its motion.

What is potential energy?

Potential energy is the stored energy of an object due to its position or condition.

What is Newton's second law of motion?

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
