Newton's Second Law of Motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be summarized by 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 means that force equals mass times acceleration.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be caused by a change in speed, direction, or both.

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

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 (using the formula A=F/M).

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

When a constant force is applied, an increase in mass results in a decrease in acceleration.

Front

What causes a falling object to accelerate?

Back

A falling object accelerates due to the force of gravity acting on it.

Front

What happens to the acceleration of an object if the net force acting on it is doubled?

Back

If the net force is doubled, the acceleration of the object also doubles, assuming mass remains constant.

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 changing the direction of an object's velocity affect its motion?

Back

Changing the direction of an object's velocity changes its velocity, which can result in acceleration even if its speed remains constant.
