Newtons Second Law

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (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 shows that force is directly proportional to both mass and acceleration.

Front

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

Back

The unit of force is the Newton (N).

Front

If an object has a mass of 5 kg and accelerates at 3 m/s², what is the force applied?

Back

F = ma = 5 kg * 3 m/s² = 15 N.

Front

What happens to the force if the mass of an object increases while the acceleration remains constant?

Back

The force will increase.

Front

What is the unit for mass?

Back

The unit for mass is the kilogram (kg).

Front

If a force of 10 N is applied to a 2 kg object, what is its acceleration?

Back

a = F/m = 10 N / 2 kg = 5 m/s².

Front

How does increasing acceleration affect the force required to move an object?

Back

Increasing acceleration requires a greater force to be applied to the object.

Front

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

Back

Force is the product of mass and acceleration; as either mass or acceleration increases, the force increases.

Front

If two objects have the same mass but different accelerations, which one has more force?

Back

The object with the greater acceleration has more force.
