weight *speed / stopping time example : What is the momentum of an 7 kg Bowling ball rolling at 5 m/s? (7x5=35 kg m/s) If the bowling ball rolls into a pillow and stops in 0.5 s, calculate the average force it exerts on the pillow. (35/.5=70 N)
density = mass/volume
Gradient= change in field value divided by the distance
Equation: Force=Mass X Acceleration If you are looking for the force, use the equation as is. To find the following, it's assumed that you are given the other two values: Mass= Force / Acceleration Acceleration= Force / Mass Remember your labels in your calculations.
One equation is Force/acceleration=mass
The equation is force multiplied by accelaratin
Speed= distance over time. :)
Speed= distance over time. :)
I'm afraid you're going to have to be a bit more specific. There are many equations for the various types of friction.
a=dv/dt average velocity = displacement divided by time take. so average velocity = displacement/time taken.
By calculating the discriminant of the equation and if it's negative the equation will have no solutions
When you are calculating a force.
There are a great many equations for calculating current; it depends on the context in which you need to calculate current.
V=distance divided by time
