Newton's 2nd Law Net Forces

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd 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 = mass x acceleration.

Front

What does 'net force' mean?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

How do you calculate net force?

Back

Net force can be calculated by adding all the forces acting on an object, taking into account their direction. If forces are in opposite directions, subtract the smaller force from the larger one.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If an object has a mass of 5 kg and is accelerating at 2 m/s², what is the net force acting on it?

Back

F = mass x acceleration = 5 kg x 2 m/s² = 10 N.

Front

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

Back

If the net force is zero, the object will not accelerate; it will either remain at rest or continue moving at a constant velocity.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as mass increases, acceleration decreases if the net force remains constant.

Front

What is an example of a net force acting on an object?

Back

If a 10 N force pushes a box to the right and a 4 N force pushes it to the left, the net force is 10 N - 4 N = 6 N to the right.

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula a = net force / mass.

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.
