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 at a constant velocity unless acted upon by an unbalanced force.

Front

Define inertia.

Back

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

Front

What is the formula for calculating force?

Back

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

Front

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

Back

The unit of force is the Newton (N).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

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 10 kg object experiences a force of 20 N, what is its acceleration?

Back

Acceleration (a) = Force (F) / mass (m) = 20 N / 10 kg = 2 m/s².

Front

What is the concept of balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the concept of unbalanced forces?

Back

Unbalanced forces result in a change in motion, causing an object to accelerate.

Front

What is the formula for calculating speed?

Back

Speed = distance / time.
