Answer 3

The F, the m and the a in Newton's formula are very important concepts in mechanics. The F is force, a push or pull exerted on an object. The m is mass, a measure of how much matter is in an object. And the a is acceleration, which describes how an object's velocity changes over time. Velocity, which is similar to speed, is the distance an object travels in a certain amount of time.

Let's restate Newton's first law in everyday terms:

­An object at rest will stay at rest, forever, as long as nothing pushes or pulls on it. An object in motion will stay in motion, traveling in a straight line, forever, until something pushes or pulls on it.

­The "forever" part is difficult to swallow sometimes. But imagine that you have three ramps set up as shown below. Also imagine that the ramps are infinitely long and infinitely smooth. You let a marble roll down the first ramp, which is set at a slight incline. The marble speeds up on its way down the ramp. Now, you give a gentle push to the marble going uphill on the second ramp. It slows down as it goes up. Finally, you push a marble on a ramp that represents the middle state ­between the first two -- in other words, a ramp that is perfectly horizontal. In this case, the marble will neither slow down nor speed up. In fact, it should keep rolling. Forever.

so its the dump truck
