Project 1 Write an essay of 1500 words, giving credible references on the use of physics in your daily activities. You need to mention 5 or more activities where physics is used. Remember to follow the APA style and give references. Physics is used in so many ways that most people do not even realize that they are using it. Even a stay at home mom uses physics more than one would think. Daily activities that many people do include physics without thinking about it, such as driving a car, using

WORKSHEET 3 WORK AND POWER Key Concepts: WORK (W) – is the PRODUCT of the net FORCE (F) applied and the DISTANCE (d) it travels in the direction of Force. In equation WORK = force x distance , (W = Fd) POWER (P) – is the RATE (t) of the doing WORK (W). The FASTER the WORK is done, the GREATER the POWER. In equation: Power (P) = WORK (W) / time (t) * Amount of power does not show the amount of work done. It just gives the time that work requires. WATTS - unit

assuming only that the net frictional torque on a rotating flywheel is constant. In performing this experiment, you will develop understanding of: ! rotational dynamics; ! evaluation of errors in measurements that may be difficult to obtain; ! estimation of a geometrically calculated quantity using simplified models. THEORY The basic equations for angular motion can often be obtained simply from those for linear motion by making the following substitutions: Linear variables Force, F Mass, m Velocity

Exp # 7 Impact of Jet Objectives : • Study the relation between the force produced and the change of momentum when a jet strikes a vane. • Compare between force exerted by a jet on a flat plate and on a hemispherical surface. Abstract The deflectors used in this experiment can be categorised into three geometries. Flat, hemisphere and Vane deflectors are used for this experiment. Calculated force , Fth and the percentage of error will be calculated in this experiment. Theory :

using real life experiments such as the mass pulley system using the Atwood’s machine and using springs (2) in series and parallel to determine their spring constants and extensions when a mass is hanged from them. Newron’s second law states that the force on an object is directly proportional to the rate of change of momentum, which later gives the formula F =ma , m= mass and a is acceleration. Newton;s third law suggests that every action occurring on an object has an equal and opposite reaction when

magnitude of the force per meter of length on a straight wire carrying an 8.40 A current when perpendicular to a 0.90 T uniform magnetic field? (b) What if the angle between the wire and field is 45.0°? [Answer: (a) 7.6 N m–1; (b) 5.3 N m–1] 2. A 1.5 m length of wire carrying 4.5 A of current is oriented horizontally. At that point on the Earth’s surface, the dip angle of the Earth’s magnetic field makes an angle of 38° to the wire. Estimate the magnitude of the magnetic force on the wire
