Is there any time lag between action and reaction?
1 Answer. At any instant in time the action and reaction forces are equal – but since as Sofia pointed out they act on different bodies, that doesn’t mean they “cancel out”: each of the bodies experiences one of the forces and accelerates accordingly.
How is action and reaction measured?
The law of action-reaction (Newton’s third law) explains the nature of the forces between the two interacting objects. According to the law, the force exerted by object 1 upon object 2 is equal in magnitude and opposite in direction to the force exerted by object 2 upon object 1.
Why can we accelerate forward when starting to run?
Which best explains why we are able to accelerate forward when starting to run? As one leg moves backward, it provides an equal and opposite force for the other foot to move forward. No acceleration takes place. Runners are always at a fixed velocity.
How does Newton’s second law apply to tug of war?
Once one side pulling on the rope exerts more force and therefore more pull, the other side has to increase their pull to try and get the rope back. This is Newton’s second law of motion which mathematically equates force as mass times acceleration.
Which of the following force is most important to win the tug of war?
The normal force is the force with which the two surfaces are pushed together. In the case of this simple tug of war above, the ground pushes up with a force equal to the gravitational weight of the person. This means that heavier people will have a greater frictional force acting to help win a tug of war.
What was the difference between Zoe’s first and second golfing attempts in terms of force?
In Zoe’s first attempt she used the right amount of STRENGTH when applying a force to the ball, but did not know the right direction because she was wearing a blindfold. In Zoe’s second attempt she applied just the right amount of strength and knew the right direction to win. (A force has both strength and direction.)
