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. It can be expressed with the formula F = m * a.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does the term 'force' mean in physics?

Back

A force is a push or pull on an object that can cause it to accelerate.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

If a 10 kg object has a force of 50 N applied to it, what is its acceleration?

Back

5 m/s² (using F = m * a).

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

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

Front

What is the formula for calculating weight?

Back

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

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

What is inertia?

Back

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