Newton's Laws

Front

What is Newton's First 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 a net external force.

Front

What is the formula to calculate force?

Back

Force (F) = Mass (m) × Acceleration (a)

Front

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

Back

Newton (N)

Front

What does inertia refer to in physics?

Back

Inertia is the property of matter that resists changes in motion.

Front

What is Newton's Second 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.

Front

If a force of 10 N is applied to a mass of 2 kg, what is the acceleration?

Back

Acceleration = Force / Mass = 10 N / 2 kg = 5 m/s².

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight (W) = Mass (m) × Gravitational acceleration (g).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant velocity.

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².
