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 at a constant velocity 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 inertia?

Back

The resistance of an object to any change in its motion.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked; the force of the kick is greater than the friction opposing it.

Front

What is the formula for calculating force?

Back

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

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

The force of gravity acting on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).

Front

What is gravitational force?

Back

The attractive force between two objects due to their masses.
