1)Do forces always result in motion? 2)What are the conditions for an object to stay at rest to keep moving at constant velocity or to move with? 3)How is force related to acceleration?
In the final example of the last section, we saw how we could calculate a dynamic acceleration based on a vector pointing from a circle on the screen to the mouse position. The resulting motion resembled a magnetic attraction between circle and mouse, as if some force were pulling the circle in towards the mouse.
In this section, we will formalize our understanding of the concept of a force and its relationship to acceleration. Our goal, by the end of this, is to understand how to make multiple objects move around the screen and respond to a variety of environmental forces.
Before we begin examining the practical realities of simulating forces in code, let’s take a conceptual look at what it means to be a force in the real world. Just like the word “vector,” “force” is often used to mean a variety of things. It can indicate a powerful intensity, as in “She pushed the boulder with great force” or “He spoke forcefully.” The definition of force that we care about is much more formal and comes from Isaac Newton’s laws of motion:
A force is a vector that causes an object with mass to accelerate.
The good news here is that we recognize the first part of the definition: a force is a vector. Thank goodness we just spent a whole section learning what a vector is and how to program with PVectors!
Let’s look at Newton's three laws of motion in relation to the concept of a force.
ln a short answer,yes.Once you apply a force to an object,it will move.
But in fact,there is a little more to the equation.You see,Newton's second law of motion states that you have to add up all the forces acting upon a system so see what will happen to it.lf the answer is zero,ax in one force pulling one way and the other pulling the opposite direction exactly,then those forces will basically cancel each other out.
So yes,forces will always result in motion,unless there is another force exactly opposed to it.
3)Howisforcerelatedtoacceleration?
Force is related to acceleration through the equation F-ma."F"stands for force,"m" stands for mass and "a" stands for acceleration.Force is a push or pull that an object can exert on other objects.Acceleration is the rate of change of an object's speed.
