  1. • Kinematics – branch of physics; study of motion • Position (x) – where you are located • Distance (d) – how far you have traveled, regardless of direction • Displacement (Dx) – where you are in relation to where you started Distance vs. Displacement • You drive the path, and your odometer goes up by 8 miles (your distance).

  2. c. Rescind a motion previously adopted: Voids a motion previously passed. "I move to rescind the motion passed at the last meeting relating to where we will go on the ski trip." d. Take from the table: Allows the assembly to resume consideration of a motion previously laid on the table. "I move to take from the table the motion

  3. If motion is uniform and object takes time t to execute motion, then it has tangential velocity of magnitude v given by v = s t f = 1 T Period of motion T = time to complete one revolution (units: s) Frequency f = number of revolutions per second (units: s–1 or Hz) 4

  4. Newton’s Second law of motion: If any force generates a change in motion, a double force will generate double change in the motion, a triple force will correspond to triple change in the motion, whether that force is impressed altogether and at once or gradually or successively. Suppose that a force is applied to a body for a time interval t ...

  5. NEWTON’S LAWS OF MOTION Background: • Aristotle believed that the natural state of motion for objects on the earth was one of rest . In other words, objects needed a force to be kept in motion. • Galileo studied motion of objects rolling down an inclined plane with smooth surfaces. He

  6. Let’s look at various aspects of simple harmonic motion including energy, motion, relationship with circular motion, and relationship with pendulum motion. 1.1 ENERGY OF SIMPLE HARMONIC MOTION The simple harmonic oscillator is an example of conservation of mechanical energy. When the spring is stretched it has only potential energy U = (1/2)kx2 =

  7. It is defined as the rate of change in angular displacement of a particle in a circular motion. It is denoted by. ω = lim ∆t→0 (∆θ/∆t) = dθ/dt. Angular velocity is measured in rad/s. Apart from angular velocity and angular speed, a particle in circular motion also possesses linear velocity and corresponding linear speed. v = d s /dt.
