Question

A flat-bed truck is traveling horizontally to the right with a crate in the back. When the truck starts to
slow down, the crate on the (frictionless) truck bed starts to slide. In what direction is the net force on
the crate?

Answer 1

Answer:

No direction

Explanation:

Net force is the sum of the vector forces acting on a body or particle. The net force is a single force replacing the impact of the initial forces on the movement of the particle. It provides the particle the same acceleration as all the real forces together as explained by the second law of movement of the Newton.

Thus, when the truck bed starts to slide there will be no direction as the net force is zero.
