PHY 1103 Physics I RKMC - HCT Learning Outcome 1: Sub-outcome 1: Assign given basic units to their corresponding physical quantities. All engineers must use the same language in their communications‚ and one of these universal communication tools is the units of measurements. Physical quantities such as length‚ weight‚ time‚ speed‚ force‚ and mass are measured with standard units. Therefore the magnitude if a physical quantity is given by a number and standard unit of measurement

Problem solving process part I There currently is an issue that I deal with at work on a daily bases. You see as a leader and a member of management there will always be people who want to see you fail at your job. This is the case for me. There is an individual that on regular bases has an issue with how I run my service department. This person seems to think that it is my main objective to not get his work orders completed‚ when in fact this is not the case. You see this particular person

Knowing that the braking forces of the tractor and the trailer are 16 kN and 60 kN‚ respectively‚ determine: (a) the distance traveled by the tractor-trailer before it comes to a stop‚ (b) the horizontal component of the force in the hitch between the tractor and the trailer while they are slowing down. -2- Problem (2) The system shown is initially at rest.

1 Velocity‚ Speed‚ Acceleration‚ and Deceleration The goal for today is to better understand what we mean by terms such as velocity‚ speed‚ acceleration‚ and deceleration. Let’s start with an example‚ namely the motion of a ball thrown upward and then acted upon by gravity. A major source of confusion in problems of this sort has to do with blurring the distinction between speed and velocity. The speed s is‚ by definition‚ the magnitude of the velocity vector: s := |v|. Note the contrast: –

Lab 1‚ problem 3: Motion Down an Incline Shaoren Yuan October 5‚ 2013 Physics 1301W‚ professor: Dr. Zudov‚ TA: David Abstract The processes of a cart rolling up and returning back along a track were recorded‚ and the processes (motion of the cart.) were described as equations. Also‚ we calculated the accelerations of every stage (aup‚ adown and ahighest). Then the relationship among aup‚ adown and ahighest was concluded. Finally‚ the acceleration was measured and was proved from data. Introduction

the blood in the opposite direction) a maximum? Hint 1. How to read the graph The graph is acceleration versus time. Remember that velocity is the signed area under the acceleration curve. As long as the acceleration is positive‚ the speed is increasing. Once the acceleration becomes negative‚ the speed will begin to decrease back to zero. ANSWER: 3 Correct Problem 2.6 Geology. Earthquakes produce several types of shock waves. The most well-known are the P-waves (P for primary http://session.masteringphysics

shows that the motion is non uniform. The car is not travelling at a constant velocity as the graph is not a straight line. A straight line graph would indicate that the motion is uniform as the position increase is constant throughout. However‚ the graph of the toy car is a curve that becomes steeper as the time increases. This suggests that the motion increases more and more as time passes‚ showing that the velocity is increased each second. As the car is also moving in the positive direction‚

the graph on the right‚ line one is a line moving at a slower velocity compared to line 2 which is moving at a faster velocity in the same about time. There is a small error in this experiment‚ as you can see in the graph of the right‚ the velocity is not as constant. 5. What is the definition of velocity? Velocity is a vector quantity that has the same direction as the displacement. Displacement per unit time is called Velocity. 6. What did you have to do to

Cart on an Incline Lab Kennedy Van Allen SPH 4U1 February 20‚ 2014 M. Reid Purpose: To determine both qualitative and quantitative properties of the motion of a cart on an inclined plane on position vs. time‚ velocity vs. time and acceleration vs. time graphs. Question: Which properties of the cart’s motion can be determined from examining each of the three graphs? Hypothesis: The predictions on the type of motion demonstrated by the cart-qualitatively- are shown below.
