physics newtons laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's Second Law of Motion?

Back

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 the formula for calculating net force?

Back

Net force (F) is calculated as the product of mass (m) and acceleration (a): F = ma.

Front

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

Back

The unit of force is the Newton (N).

Front

What does Newton's Third Law of Motion state?

Back

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

Front

What is thrust in the context of rocket propulsion?

Back

Thrust is the force that propels a rocket forward, generated by expelling gases at high speed.

Front

How does mass affect acceleration when the same force is applied?

Back

A lighter object will accelerate more than a heavier object when the same force is applied.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; increasing mass decreases acceleration if force is constant.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
