(2024) NGSS Physics Fall Final Review

The law states that the total momentum of a closed system before a collision is equal to the total momentum after the collision.

Mass (m) can be calculated using Newton's second law: m = F/a, where F is the net force and a is the acceleration.

The gravitational force increases; specifically, it is proportional to the product of the masses.

F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

The object is either at rest or moving with a constant velocity (it is in equilibrium).

The electric force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

The unit of force is the Newton (N).

To convert grams to kilograms, divide the number of grams by 1000.

The acceleration due to gravity on Earth is approximately 9.81 m/s².
