The speed of the particle is proportional to = √t
Work = the change in kinetic energy = 1/2 mv2
If work is proportional to time
W = t
1/2 mv2 = t
v2 = t
v (speed) = √t
Speed is the time rate at which an object is shifting along a path, even as speed is the fee and route of an item's movement. Positioned every other manner, speed is a scalar value, even as pace is a vector.
Velocity (or price, r) is a scalar quantity that measures the gap traveled (d) over the alternate in time (Δt), represented via the equation r = d/Δt.
The Italian physicist Galileo Galilei is credited with being the first to measure speed by considering the gap blanketed and the time it takes. Galileo described pace as the gap covered in line with unit of time.

Answer:
- 144 V
Explanation:
A = (2, 3) m = 2 i + 3 j
B = (5, 7) m = 5 i + 7 j
Displacement vector = AB = B - A = (3 i + 4 j) m
Electric field, E = (4 i + 3 j ) N/C
V = - E . AB
V = - (4 i + 3 j) . (3 i + 4 j)
V = - (12 + 12) = - 144 V
Answer:
New force, 
Explanation:
It is given that,
Force acting between two charged particles, 
We need to find the force if they are moved so they are only one-eighth as far apart.
The force between two charged particles separated at a distance of r is given by :
............(1)
If the charges are one-eighth as far apart then, r' =(1/8)r and new force is given by :
..........(2)
Dividing equation (1) and (2) :
F' = 48000 N
or
Hence, this is the required solution.
The total energy equation would be Kinetic energy+Potential energy
