The equation for frictonal force is F frict= micro___x normal force. The equation for gravitational force is Fgrav= m x g.
Mass x gravity (10 m/s)
The equation for momentum is p= m x v.
the "p" is for momentum. it must be lowercase beacuse Uppercase is for something else. "m" is for mass. "v" is for velocity.
The equation for kenetic energy is KE= 1 / 2xmxvsquared. KE is for kenatic energy. m is for mass. v squared is for velocity.
The equation for newton's second law of motion is F net= m x a
F net is for net force. M is for mass. A is for accaleration.
[edit] question
What would the magnitude of the normal force be on a box, with mass M, on a ramp that is 30 degrees from the ground? Does it matter how long the ramp is? BriEnBest (talk) 08:31, 16 February 2008 (UTC)
- This sounds like a homework question. I'll answer it in the form of a question. What is the total external force on the box? What is the component of that force normal to the ramp? —Ben FrantzDale (talk) 16:14, 16 February 2008 (UTC)
