When a traffic light turns from red to green, it takes much more force and time for a large truck to get going than it does a small, compact car. This is an example of which law of motion?

First Law of Motion.

Explanation:

Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.

In physics, Sir Isaac Newton's First Law of Motion is known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

The inertia of a physical object such as a truck is greatly dependent or influenced by its mass; the higher the quantity of matter in a truck, the greater will be its tendency to continuously remain at rest.

Hence, it would take much more force and time for a large truck to get going when the traffic light turns green than it does for a small, compact car. This is an example of the first law of motion.

less than one you can't create energy

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
