Question

What happens when more than one force is acting on a body?​

Answer 1

Answer:

When more than one force acts on an object, the forces combine to form a net force. The combination of all the forces acting on an object is the net force. If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement.

Answer 2

Answer:

If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone.

Explanation:

simple ..

using Newtonian formula

mass = force times acceleration which algebraically becomes

force = mass divided by acceleration

so each force will accelerate the object in the direction in which it acts

its a vector sum so there is a calculable single resultant force and consequently the body accelerates in a single direction.

This result is most easily calculated using the ‘triangle’ of forces by joining together scaled arrows depicting all the forces.
