Chapter 4 – Linear Motion Reading Assignment Section 4.1 –Motion Is Relative 1. How can you describe motion? 2. Describe motion in terms of space shuttle? What is it relative to? A race car? 3. How can you be both at rest and also moving about 107‚000 km/h at the same time? 4. When you describe the speed of anything what are you actually describing? 5. How can you tell that an object is moving? 6. You cover 10 meters in 1 second. Is your speed the same if you cover 20 meters in 2 seconds? Section

motion are time‚ position‚ displacement‚ velocity and acceleration. Newton has described objects in motion in balanced and unbalanced state. There is equilibrium to the object with balanced forces that are acting on it. He said that the object will never accelerate if there will be no net force acting on it. Thus‚ the velocity is constant and its acceleration is always zero. In the Second Law of Motion‚ he showed that an object will have acceleration due to unbalanced forces acting on it. There are two

a = = (Acceleration) b. a = Δv = vf – vi = – = Δt = tf – ti = 0.525s – 0.4s = 0.125s a = = (Deceleration) c. a = Δv = vf – vi = – = Δt = tf – ti = 1.1s – 0.55s = 0.55s a = = (No acceleration) b) Questions a => g a. Our line of best fit (in each section‚ in this case section a) is a straight line. This indicates that there was constant positive acceleration b. a = Δv = vf – vi = – 0 = Δt = tf –

Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude of the net force‚ and inversely proportional

is moving with a uniform speed c) When the body is moving with a non-uniform speed. 4. The brakes applied to a car produced an acceleration of 6 ms-2 in the opposite direction of the motion. If the car takes 2s to stop after the application of brakes‚ calculate the distance it travels during this time. 5. What is positive acceleration and negative acceleration? 6. Why is the motion of Satellites around their planets considered an accelerated motion? 7. Study the time (t) versus distance

Acceleration Velocity Displacement Distance Time Definition 1. Acceleration is the rate of change of velocity with time. Velocity is a vector physical quantity; both magnitude and direction are required to define it. the length of an imaginary straight path‚ typically distinct from the path actually travelled by P. Distance is a numerical description of how far apart objects are. In physics or everyday usage‚ distance may refer to a physical length‚ or an estimation Time in physics is

first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the second experiment‚ acceleration of a cart traveling down a slight incline was measured with a two photogate method. Gravity was calculated and yielded

Sub-outcome 3: Derive units of speed‚ acceleration‚ force‚ density‚ area‚ volume from basic units. The Derived Units: From the base SI units‚ many units for other physical quantities were derived. A derived unit is a unit that is defined by a simple combination of one or more of base units

Based on these measurements‚ the acceleration of the blood ejected by the heart can be determined. Patients with low blood accelerations generally have weakened heart muscles. A sketch of a single cycle of a ballistocardiogram is given in the figure. . The units of the graph are arbitrary and linear for both time‚ ‚ and acceleration‚ . Part A At what time (in the arbitrary
