What is a difference between distance and displacement

Displacement can be equal to zero if the object ends in the place it began in

Distance is always shorter than displacement

Distance can be equal to infinite when only a small distance has been travelled

Why is the net force 0 in the image?

Because they are both pulling the same amount of force in opposite directions

What is Newtons first law of motion?

An object in motion will stay in motion until the object is acted upon.

For every action there is a equal and opposite re-action.

In the picture, the blocks are flying out of the truck based on Newton's first laws because .....

object in motion stays in motion

When an unbalanced force acts on an object, the force ______________________.

changes the motion of the object

does not change the motion of an object

is equal to the weight of the object

1. Why does a rider on horseback fall when the horse starts running all of a sudden?

The lower body of the rider moves forward with the horse but the inertia of rest keep the upper body at rest

What are balanced forces?

When two forces acting on an object are equal in size but act in opposite directions along the same line

When two forces acting on an object are different in size but act in opposite directions along the same line

When three forces acting on an object are equal in size but act in opposite directions along the same size
