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. It can be expressed as F = ma.

Front

What is the unit for force?

Back

The unit for force is Newtons (N).

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) can be calculated using the formula a = F/m, where F is the net force and m is the mass.

Front

If a 10 kg object experiences a force of 50 N, what is its acceleration?

Back

5 m/s² (using a = F/m = 50 N / 10 kg).

Front

What does it mean if an object has a greater mass in terms of acceleration?

Back

For the same force applied, an object with greater mass will have less acceleration compared to an object with lesser mass.

Front

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

Back

As mass increases, acceleration decreases if the force remains constant.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes objects to accelerate downwards at approximately 9.81 m/s², increasing their speed as they fall.

Front

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

Back

The acceleration of the object will also double, assuming mass remains constant.

Front

If two objects of different masses are pushed with the same force, which will accelerate more?

Back

The object with the lesser mass will accelerate more.

Front

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 after all opposing forces are considered, and it determines the object's acceleration.
