The area under a force-time graph is force multiplied by time, which is a quantity called impulse. Impulse is equal to the change in momentum of an object. So you can figure out how much the momentum changes by finding the area under a force-time graph.
Q. What is area under force-displacement graph?
The area under the force-displacement curve represents the work done. It is the distance (s) of the object displaced by the application of the force (f). In this case force (f) is presented on the y-axis and displacement (s) on the x-axis. The work done (w) is a scalar quantity.

Q. What is a force vs displacement graph?
A force-displacement graph will have force (in N) on the vertical axis and displacement (in m) on the horizontal axis. The area of the graph is = Fs. This quantity represents the work done on the object. This is equal to the kinetic or potential energy the object gains due to the application of the force.
Q. What is the formula for charge in physics?
Charge is measured in coulombs, C. The charge of an electron is 1.6 x 10 -19 C….The relationship between current I and quantity of charge Q.
| I = | I = Q ÷ t |
|---|---|
| Q = It | Q = I x t |
| t = | t = Q ÷ I |
Q. What units are used for Q in physics?
| Electric charge | |
|---|---|
| Common symbols | q |
| SI unit | coulomb |
| Other units | elementary charge faraday ampere hour |
| In SI base units | C = A⋅s |
Q. How do you calculate Q in thermodynamics?
In equation form, the first law of thermodynamics is ΔU = Q − W. Here ΔU is the change in internal energy U of the system. Q is the net heat transferred into the system—that is, Q is the sum of all heat transfer into and out of the system.
