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

Front

What is the formula to calculate force?

Back

The formula to calculate force is F = ma, where F is force, m is mass, and a is acceleration.

Front

If a 5 kg mass is pushed by a 10 N force, what is the acceleration?

Back

The acceleration is 2 m/s².

Front

How much force is needed to accelerate a 12 kg mass at 5 m/s²?

Back

The required force is 60 N.

Front

What is the acceleration of a 10 kg mass pushed by a 5 N force?

Back

The acceleration is 0.5 m/s².

Front

What is the mass of an object that requires 100 N of force to accelerate at 10 m/s²?

Back

The mass is 10 kg.

Front

What does it mean for an object to have a net force acting on it?

Back

A net force acting on an object means that the total force acting on the object is not zero, resulting in a change in the object's motion.

Front

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

Back

In Newton's Second Law, as mass increases, acceleration decreases for a given force, and vice versa.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

How does friction affect the acceleration of an object?

Back

Friction opposes the motion of an object, reducing its acceleration for a given applied force.
