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

SPH4U-B 4 Circular Motion Physics SPH4U-B Lesson 4 Introduction Transportation has undoubtedly advanced. Not only have vehicles changed‚ but the means by which people can get themselves to and from different locations has changed as well. Maps and compasses now take a backseat to the Global Positioning System (GPS). Access to the GPS is now very widespread; 24 satellites above our atmosphere are used to send and receive information in order to accurately determine locations of

during its motion. Is the acceleration of a simple harmonic oscillator ever zero? If so‚ when? What about a damped harmonic? Yes. At the point in the center‚ the acceleration drops to zero and changes direction when the velocity changes from increasing to decreasing. The acceleration is zero as it crosses the equilibrium point. Yes; the acceleration is zero when the velocity is at its maximum‚ that is‚ at the equilibrium position. Since the force and hence the acceleration always act TOWARDS the equilibrium

PURPOSE/QUESTION Apply kinematics equations for constant acceleration to find your reaction time. How much is it? How does reaction time change with practice? THEORETICAL The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction. Displacement is the moving of something from its place or position. Free fall acceleration is when there is no air resistance affecting an object

message is sent to the owner of the vehicle. In accident identification system a microcontroller is placed to identify the amount of damage caused to a vehicle in case of accident. This happens by a dedicated acceleration identification IC. In case of accident‚ the change in the acceleration is assessed and the amount of damage calculated. After this the alarm signal is transmitted through an RF transmitter if the accident is found to be very high. An RF receiver is placed at any station (hospital

product of the mass and the acceleration of the object. However‚ the performance’s result would be measured acceleration instead the net force. During this experiment‚ the objects are two weight hangers with a same origin mass which is 5g and later have total mass is around 2000g. The experiment is performed by transferring mass from one to another hanger and calculates the time the right hanger takes to hit the ground. Then‚ students start to calculate the measured acceleration and predicted one. Objectively
