Chapter 7 & 8
How to eliminate vectors to get the magnitude of the Force?
Take the squared product of the x component and the y squared product, sum them, then take the square root of the number.
to find the magnitude of C given
C = (A)x + (B)y
Newton unit (N)
The magnitude of one vector time the magnitude of the other vector times the cosine of the angle between the two vectors.
Work is positive
when Force and component are going in the same direction'
Work is negative
when the force and the component in the direction of motion is opposite
Work is zero
When Force and the component of motion are at a 90 degree angle
