Newton's Laws of Motion

Front

What does Newton's First Law of Motion state?

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 force?

Back

Force (F) = mass (m) × acceleration (a).

Front

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

Back

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 the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

If a 10 kg object is accelerating at 5 m/s², what is the net force acting on it?

Back

50 Newtons (F = ma = 10 kg × 5 m/s²).

Front

What is the effect of friction on motion according to Newton's laws?

Back

Friction opposes the motion of objects and can affect their acceleration.

Front

How does mass affect acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the force remains constant.
