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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is 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 weight?

Back

Weight (W) = mass (m) × acceleration due to gravity (g).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

How does mass affect inertia?

Back

As mass increases, inertia increases, making it harder to change the object's state of motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

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

Back

According to Newton's Second Law, force equals mass times acceleration (F=ma).

Front

What happens to an object in free fall?

Back

An object in free fall accelerates downward at 9.8 m/s² due to gravity.
