Why every action has reaction?
Every action has an equal and opposite reaction to achieve Equilibrium where the forces sum to zero.
What is the sum of action and reaction on a body and explain?
The sum of action and reaction on a body is zero according to Newton's third law of motion. This law states that for every action, there is an equal and opposite reaction. This is because the action and reaction forces act on different objects, resulting in a net force of zero on the system as a whole.
Action and reaction are equal and opposite then how motion occurs?
Motion - or rather acceleration - occurs as a result of a net force, meaning that the vector sum of forces on an object is non-zero. This is unrelated to "action and reaction"; please note that "action" and "reaction" occur on DIFFERENT OBJECTS.
Why the book stay stationary on table altough action and reaction forces are applied?
The action and reaction forces have equal magnitudes and opposite directions, so their vector sum is zero. We say the two forces are "balanced", and the net force on the book is zero, so the book doesn't accelerate.
How can you obtain third equation of motion from first equation?
The 1st and 3rd Equation of motion are the same, the force is zero. Thus 0 =force = Sum forces = action + reaction =0
Does action-reaction force cancel fr a net force of zero?
Yes.
What is Newton's thirdlaw of motion?
Newton's 3rd Law is "for every action there is an equal and oposite re-action". This is the sum of the vector forces is zero.
What is the sum of zero?
It is zero.
What is the momentum law?
The Momentum Law is Newton's 3 rd Law Action-Reaction,The sum of the forces is zero. 0 = F1 + F2 = d(p1 +p2)/dt gives teh Momentum Law: p1 + p2 = constant.
Is the sum of zero and a number zero?
No, the product is, but not the sum. 0 + 2 = 2
What is the difference between balanced forces and action and reaction forces?
"Action and reaction" refers to Newton's Third Law. Forces always come in pairs; if object "A" pushes against object "B", then object "B" will push back against object "A". Which of these two forces is called the "action", and which the "reaction", is often arbitrary."Balanced forces" is unrelated to the above; when forces are "balanced", it means that the vector sum of all the forces that act on the same object are zero. Please note that "action and reaction" forces are forces that act on different objects, so the forces on a single object are not necessarily balanced.
When a ball bounces off a wall the net force on the ball is zero because of action and reaction forces.?
False!
