Newton's Second Law

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. This is often expressed as F = ma.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force, meaning more force is required to achieve the same acceleration.

What is inertia?

Back

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

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; greater force results in greater acceleration if mass is constant.

What happens to an object's motion if no net force acts on it?

Back

If no net force acts on an object, it will maintain its current state of motion, either at rest or moving at a constant velocity.

Front

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

Back

The unit of force is the Newton (N).

Front

How does Newton's Second Law apply to real-world situations?

Back

It can be used to calculate the acceleration of objects when forces are applied, such as in vehicle dynamics, sports, and engineering.

What is the significance of the net force in Newton's Second Law?

Back

The net force is the total force acting on an object, and it determines the object's acceleration.

Can an object have force applied to it and not accelerate?

Back

Yes, if the forces are balanced (net force is zero), the object will not accelerate.
