- 2. Speed and Velocity The rate of change of distance is called speedv = dtDistance traveled (m)Time taken (sec)Speed (m/sec)
- 3. Velocity Velocity …..Rate of change of displacement.A speed in a given directionVelocityDirectionMagnitude(speed)Velocity isa VectorQuantity
- 4. Speed and VelocityPilots concern velocity(Direction & Speed).Speed = 300 km h–1Direction = westMTR drivers concern speed only.Speed = 90 km h–1 Speed is a single measurement that tells how fastyou aregoing, like 90 km/h. Velocity means you know both your speed and your
- 5. AccelerationAcceleration is a vector quantity that is defined as therate at which an object changes its velocity . An object isaccelerating if it is changing its velocity.a = v - utChange in speed (m/sec)Change in time (sec)Acceleration(m/sec2)
- 6. Accelerations of a CarAcceleration is the rate ofchange in the speed of an object.
- 7. Velocity-Time Relation(v = u + at)If the motion is considered from t = 0, then thecorresponding velocity v(o) at t = 0 is calledthe initial velocity and the velocity after atime interval t, is called the final velocity anddenoted by v(t) . In this case, the accelerationis given byor at = v (t) - v (0)v(t) = v (0) + atif we say that initial velocity is denoted at u and final velocity is vThanv = u + at
