What is the difference between impulse and force?
Force is a push or pull that causes an object to move or change its motion, while impulse is the change in momentum of an object when a force is applied over a period of time. In other words, force is the cause of motion, while impulse is the effect of a force acting over time.
How specialization advantageous?
Specialization is advantageous because a single task can be done in a short time and very well.
If the magnitude of applied force falls short of required centripetal force then the object will move away from the centre of the circle?
Yes. It would spiral away such that the radius of rotation will increase, until the radius is large enough for the centripetal force to decrease to the applied force. (Centripetal force= mv2/r)
Which causes a bigger change in momentum of an object a big force for a short time or a small force for a longer time?
A big force applied for a short time causes a bigger change in momentum compared to a small force applied for a longer time. This is because momentum is the product of force and time, so a larger force produces a greater change in momentum in a shorter duration.
What are the vests for karate called?
"DOGI" Gi for short.
What is an impulse in scientific terms?
Impulse is force x time where the assumption is that the force is high and the time is short. Since force is rate of change of momentum of a free body, then impulse amounts to a sudden change of its momentum.
Does a long ramp or short ramp require less force?
A long ramp typically requires less force to move an object up it compared to a short ramp. This is because a longer ramp allows the force to be applied over a greater distance, reducing the amount of force needed to overcome gravity and friction.
What early 80's tv show had a karate man in a van?
You may be referring to a short lived TV show called The Master. It was ninjitsu, not karate.
Why is it easier to pull out a nail with a long-handled hammer than with a short- handled hammer?
A long-handled hammer provides more leverage, making it easier to apply a greater force to the nail. This increased force helps to loosen the nail more effectively compared to a short-handled hammer, where less force can be applied.
What is impulse in physics?
Impulse is the change in momentum of an object when a force is applied over a period of time. It is calculated by multiplying the force applied by the time it is applied for. Impulse is a vector quantity and can cause an object to change its velocity.

Does learning karate makes someone short?
No, that is rediculous...how would learning anything make you shrink?
