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

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

Front

What factors affect friction?

Back

The amount of force pressing the surfaces together and the roughness of the surfaces.

Front

How does friction affect motion?

Back

Friction opposes motion, meaning more friction decreases speed.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

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

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass have greater inertia.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).
