Newton's Laws Review

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, which also indicates its inertia. Objects with greater mass have greater inertia.

Front

What does Fn stand for in physics?

Back

Fn stands for Force normal, which is the force exerted by a surface to support the weight of an object resting on it.

Front

What is the relationship between force and acceleration?

Back

To increase acceleration, you need to increase the force applied to an object, according to Newton's second law of motion (F=ma).

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mass (m) × velocity (v).

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration of an object moving in a circular path, directed toward the center of the circle.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is Newton's first law of motion?

Back

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's second law of motion?

Back

Newton's second law 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).

Front

What is Newton's third law of motion?

Back

Newton's third law states that for every action, there is an equal and opposite reaction.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m × a, where F is force, m is mass, and a is acceleration.
