## Writing Force Equations Writing as long as ce equations Lets try it This one has a little twist Resolving vectors into components.

Morales, Melinda, Features Editor has reference to this Academic Journal, PHwiki organized this Journal Writing Force EquationsWriting as long as ce equationsDraw a FBD to identify all as long as ces in addition to the directions they actWrite an equation to sum up the horizontal as long as ces making sure all as long as ces that affect the object horizontally are accounted as long as in the equation. – algebraic signs are used to indicate directions – Keep in mind when in equilibrium, F = 0Write an equation as long as the vertical as long as ces making sure all as long as ces that affect the object vertically are accounted as long as in the equationLets try it A book is pushed to the right across the desktop at a constant speed.

This one has a little twist Sally is pushing a shopping cart downward in addition to to the right at an angle of 40 degrees to the ground. The cart is moving at a constant speed. Lets review some vector math be as long as e attempting this oneResolving vectors into components.Every vector can be visualized as the hypotenuse of a right triangle. See the red arrows below.Resolving a vector means to find the sides of this right triangle its like working backwards to find the parts that would add to as long as m the original vectorResolving vectors into components60 N40°What are the horizontal in addition to vertical components of the tension in the chain

This one has a little twist Sally is pushing a shopping cart downward in addition to to the right at an angle of 40 degrees to the ground. The cart is moving at a constant speed. Example ProblemA 15 kg lawn mower is pushed at a constant speed by a as long as ce of 100.0N directed along the h in addition to le at 40.0° to the horizontal. Determine the frictional as long as ce acting on the mowerCalculate the normal as long as ce acting on the mowerDraw a as long as ce diagram of the mower:FNfFgFAWrite equations:FAcos – f = 0FN – FAsin – Fg = 0Use equations to solve problem:FAcos – f = 0 f = FAcos f = (100 N)cos 40.0 f = 76.6 Nb) FN – FAsin – Fg = 0 FN = FAsin + Fg FN = FAsin + mg FN = (100 N)sin 40.0 + (15 kg)(10 m/s2) FN = 214.3 N
