Newton's Laws

Front

What is Newton's 1st Law of Motion?

Back

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 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

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the gravitational force acting on that mass.

Front

What are the units for force?

Back

The SI unit for force is the Newton (N).

Front

What are the units for acceleration?

Back

The units for acceleration are meters per second squared (m/s²).

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 according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

Force is the product of mass and acceleration; increasing either mass or acceleration increases the force.
