Newtons 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 the unit of force?

Back

Newton (N) is the unit of force in the International System of Units (SI).

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the larger force.

Front

What is the formula to calculate weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

Define net force.

Back

Net force is the vector sum of all the forces acting on an object.

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 for a given net force.
