Question

Newton’s Second Law of motion defines force in terms of mass and acceleration, F= ma. Which of the following is false? The term for force in the above equation represents the net force on the object.

The forces creating the net force can lie in any direction.
The forces creating the net force must lie in the same direction.
The acceleration is directed in the same direction as the net force.
A zero net force indicates a state of equilibrium.

Answer 1

The forces creating the net force must lie in the same direction.

Step-by-step explanation:

newton's second law states that the net force acting on the body is equal to the product of mass and the acceleration of the body.

If there are several forces acting on the body in different directions, then we have to find teh net force by using the vector sum and then find the acceleration.

It is not necessary that all the forces acting in the same direction.

if they are in different directions then we have to find the net force by t=using the formula for the vector sum.
