You can calculate potential energy by:
U = m.g.h
Where, U = potential energy
m = mass
g = acceleration due to gravity
h = height
Hope this helps!
This is correct, I just did the test. Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.
The heat of fusion must be approx from 0 to infinity
Either no forces or a balanced group of forces
(not a group of "balanced forces"; there's no such thing)
Answer:
Kinetic energy would increase by a factor of 4 where as momentum would increase by a factor of 2.
Explanation:
Kinetic Energy is given by 0.5*mass*velocity^2. Kinetic Energy is proportional to Velocity^2.
Momentum is given by mass*velocity. Momentum is proportional to Velocity.
If the velocity of an object is doubled, Kinetic energy would increase by a factor of 2^2 i.e 4 times. Momentum would increase by a factor of 2.
