Newton's Laws, Gravity, Kinematics, Momentum (Final, Pt 1 of 2)

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

F = m * a (Force equals mass times acceleration).

Front

What happens to gravitational force as the distance between two objects increases?

Back

The gravitational force decreases.

Front

What does a velocity vs. time graph indicate if the velocity is 0 m/s?

Back

The object is not moving.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = m * v).

Front

How do you calculate the momentum of an object?

Back

Momentum (p) = mass (m) * velocity (v).

Front

What is the acceleration of an object if a force of 89,250 N is applied to a mass of 1785 kg?

Back

Acceleration (a) = F/m = 89,250 N / 1785 kg = 50 m/s².

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases for a constant force.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
