Newton's Laws of Motion

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 unless acted upon 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.

What is the formula for calculating force?

Back

F = M * A (Force equals mass times acceleration).

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

If a car has a mass of 1,000 kg and accelerates at 2 m/s², what is the force?

Back

F = M * A = 1,000 kg * 2 m/s² = 2,000 Newtons.

What is inertia?

Back

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

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does it mean when we say 'force pairs'?

Back

Force pairs refer to the action and reaction forces that occur simultaneously when two objects interact.

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

Back

As mass increases, acceleration decreases for a given force.
