How To Change Velocity
Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is. When analyzing the motion of an object it is crucial to first identify the type of velocity you're looking for. Average velocity measures the change in position and direction of an object over a time interval, whereas instantaneous velocity measures the velocity of an object at an instant in time. Velocity: Right click the footage, go to Insert/Remove Envelopes, click Velocity. Also, apologies for sounding dead and possibly messing something up, I have been hit with hay-fever, which is nice.
Working out some simple physics and I can't figure out how to convert velocity to newtons for force.A six pound (2.72kg) tonka truck is moving across a cardboard bridge at a constant velocity of.067m/s (estimated). I tried looking for a while but was unable to find the kinetic friction of plastic wheels on cardboard.Using newton's second law, I was able to make this equation: F-Fk=ma, so F = ma+Fk. Fk is muK.Fn, so the final equation is: F=ma+muK.fn.
What Can Change Velocity
Because there is no movement in the Y direction, fn would be the weight, and in this case 26.7n. There is no acceleration, so would ma equal zero?Is there any way to find the kinetic friction between plastic and cardboard?Thanks guys!
