Collazo 1 Asia Lee Collazo English Comp. I Professor J. Mohan February 14‚ 2013 “False Appearance’s” We are confronted with many different images of others. These false images can either be externally imposed or internally fabricated. In either case‚ one must have the courage to look through this ignorance so that ones true self can be exposed. After reading Mirrors it was obvious that‚ Lucy Grealy cared what others thought about her physical appearance. In time‚ however

happen is because of friction. The force of friction is the resistance to motion that is in the opposite direction of the traveling object. This is why if you roll a ball on the ground it eventually stops. Friction is also the reason you can hold a book‚ and the reason why you don’t slip when walking! The ground and other solid surfaces can cause friction‚ called dry friction‚ but fluids (liquids and gases) like water and air can also cause frictional forces‚ called fluid friction. The equation for

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

SUMMARY OF FRICTION The maximum force of static friction that exists between two surfaces is proportional to the normal force and mostly independent of area of contact. This situation is shown here: N = the total normal force (force perpendicular to the horizontal surface) which is essentially the weight of the object. The coefficient in that equation is called the coeffecient of static friction and that depends on the material: When the object is actually moving‚ the friction is said to be kinetic

APPLYING NEWTON’S LAWS 5.1. 5 IDENTIFY: a = 0 for each object. Apply ΣFy = ma y to each weight and to the pulley. SET UP: Take + y upward. The pulley has negligible mass. Let Tr be the tension in the rope and let Tc be the tension in the chain. EXECUTE: (a) The free-body diagram for each weight is the same and is given in Figure 5.1a. ΣFy = ma y gives Tr = w = 25.0 N. (b) The free-body diagram for the pulley is given in Figure 5.1b. Tc = 2Tr = 50.0 N. EVALUATE: The tension is the
