Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

The Law of Inertia: 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 2nd Law of Motion?

Back

The Law of Force and Acceleration: 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 3rd Law of Motion?

Back

The Law of Action and Reaction: For every action, there is an equal and opposite reaction.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) x Acceleration (a).

Front

If two forces of 20 N and 12 N act in opposite directions, what is the net force?

Back

The net force is 8 N toward the North.

Front

What happens when two objects exert equal forces on each other?

Back

They will not move at all, as the forces are balanced.

Front

What is inertia?

Back

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

Front

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

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can affect the acceleration of an object.
