Newton's 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 with the same speed and in the same direction 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.

Front

What is inertia?

Back

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

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance/Time).

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

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated by dividing the change in velocity by the time taken (a = Δv/Δt).

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion and acceleration.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass (Weight = mass × gravity).
