If a 12-N force is applied continuously through a distance
of 12m, then the amount of work done is
(force) x (distance) = (12 N) x (12 m) = 144 joules.
Power = (work done) / (time to do the work)
= (144 joules) / (3 sec) = 48 joules/sec = 48 watts.
We don't care what purpose the force was used for,
or how much friction was involved.
Answer:
True.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Simply stated, a vector quantity has both magnitude and direction.
Thus, a vector quantity is: A deer running 15 meters per second due west.
Answer:
Situation 2, 4, 5
Since there are five situations I just numbered them 1-5
An example of Newton's First Law is chewing. You need to start chewing in order for the food to become smaller which involves motion from your teeth and the food which stays in motion until you swallow the food. When you chew, you move the food in a circular motion and when you are ready to swallow, that motion stops and goes into another motion.
