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 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 does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have for a given force.

Front

What is the formula to calculate force?

Back

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

Front

What is the effect of gravity on falling objects?

Back

All objects fall at the same rate of acceleration due to gravity, approximately 9.8 m/s², regardless of their mass.

Front

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

Back

Force is the product of mass and acceleration; increasing force increases acceleration, while increasing mass decreases acceleration.

Front

What happens to a passenger in a car that suddenly stops?

Back

Due to inertia, the passenger continues moving forward until stopped by the seatbelt or another object.

Front

What is an example of Newton's Third Law of Motion?

Back

When a swimmer pushes water backwards, they move forward.
