Newton's Second Law

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that 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 = ma.

Front

What does the formula F = ma represent?

Back

F = ma represents the relationship between force (F), mass (m), and acceleration (a). It indicates that force equals mass times acceleration.

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

How do you calculate mass using Newton's Second Law?

Back

Mass can be calculated using the formula m = F/a, where F is the force applied and a is the acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

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 an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate. It occurs when the net force acting on an object is not zero.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What are the appropriate units to describe acceleration?

Back

The appropriate units to describe acceleration are meters per second squared (m/s²).

Front

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

Back

The acceleration is 5 m/s², calculated using the formula a = F/m.
