The force that was acting on the objects that dropped in the air was friction. The force that was acting on the object when it dropped in the vacuum was friction also Part two: Comparing Forces 1. Choose two forces and compare and contrast these forces. You must provide two ways that they are

PHYSICS 1 FAP0015 Questions & Answers to Physics I Assignments Chapter 1 11. What‚ roughly‚ is the percent uncertainty in the volume of a spherical beach ball whose radius is r = 2.86 ± 0.09 m? Answer: To find the approximate uncertainty in the volume‚ calculate the volume for the specified radius‚ the minimum radius‚ and the maximum radius. Subtract the extreme volumes. The uncertainty in the volume is then half this variation in volume. 3 Vspecified = 4 π rspecified = 4 π ( 2.86 m ) = 9

Disk With Weight: A 15 kg uniform disk of radius R = 0.25 m has a string wrapped around it‚ and a m = 3 kg weight is hanging on the string. The system of the weight and disk is released from rest. a) When the 3 kg weight is moving with a speed of 2.2 m/s‚ what is the kinetic energy of the entire system? KETOT = KEwheel+KEweight = (1/2)(I)(w2)+(1/2)(m*v2) =(0.5* v2)(m+1/2M) =0.5*(2.2^2)*(3+(.5*15)) J b) If the system started from rest‚

Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. It would also help in pipe

the force of gravity (acts in a downward direction)‚ the normal force (the support force exerted upon the object that is in contact with another stable object)‚ the force of movement (the force from the wheels-moment of an object) and the force of friction (the force exerted by a surface as an object moves across). According to Isaac Newton’s law of Universal Gravitation‚ objects near the surface of the earth accelerate at a rate of 9.8m/s/s towards the ground. The purpose of this investigation

to ride on. This is familiar to people who play air hockey‚ and it’s been used in lower speed transit before‚ such as the people mover in the Detroit Airport. The low pressure in the tube means that it doesn’t take a lot of power to overcome air friction and can be sustained by on board batteries (using numbers gleaned from their work with the Tesla S)‚ and the big power drain from acceleration is accommodated by Linear Induction Motors (many existing transit designs use LIMs‚ such as the Vancouver

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
