Uniform acceleration 2 = …… ? Constant velocity 3 = …… ? Uniform retardation [deceleration] Area under the graph = A = …….. ? DISTANCE TRAVELLED
© John Parkinson 7 Velocity – v/ms -1 Time – t/s QUESTION The graph represents the motion of a tube train between two stations Find 1.The acceleration 2.The maximum velocity 3.The retardation 4.The distance travelled 1. The acceleration = the initial gradient = 30÷20 = 1.5 m s The maximum velocity is read from the graph = 30 m s The retardation = the final gradient = -30 ÷ [80-50] = m s -2 4.The distance travelled = the area under the graph =½ x 20 x 30 + x + ½ x x = 1650 m

1 Using Kinematic Equations 1. Write down the symbols, values and units (in SI) of given quantities 2. Write down the symbol of the quantities required.
Graphical Analysis of Linear Motion. A car travels along a road at a constant velocity of 10. m/s time (s) position (m)
Objectives After completion, you should 1. Know the term displacement, velocity,acceleration and deceleration for motion in a straight line 2. Be familiar.
Straight Line Motion Looking at position, velocity, and acceleration from the integral.
Kinematic Equations Practice Problems. 1. An object starts from rest with a constant acceleration of 8.00 m/s/s along a straight line. Find the speed.

Kinematics: What is velocity and acceleration? Lets Review v = d t Distance traveled (m) Time taken (sec) Average Velocity (m/sec) Instantaneous Velocity:
Derivation of Kinematic Equations Where do the equations come from?
The four kinematic equations which describe an object's motion are: There are a variety of symbols used in the above equations and each symbol has a specific.

Mechanics Rotation, Angular Momentum and Gravity.
What is motion? An object is in motion when it’s distance from another object changes. What is a reference point? It is an object or place used to determine.
Acceleration! Chapter 9 Section 3. Acceleration Lets Review: What is Speed? Velocity? What is a Vector? Acceleration: RATE at which velocity changes Acceleration:
