Newton's 3 laws

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest and an object in motion will stay in motion unless acted on by a net external force.

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 Newton's Third Law of Motion?

Back

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

Front

How do you calculate mass using Newton's Second Law?

Back

Mass can be calculated using the formula m = F/a, where F is the net force and a is the acceleration.

Front

What is the formula for calculating net force?

Back

Net force can be calculated using the formula F_net = m * a, where m is mass and a is acceleration.

Front

What does it mean for a force to be unbalanced?

Back

An unbalanced force results in a change in the motion of an object, causing it to accelerate.

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 is the significance of the direction of force in motion?

Back

The direction of the net force determines the direction of the object's acceleration and movement.

Front

What is inertia?

Back

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

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, for a given force, the acceleration decreases.
