UNIT III. KINEMATICS

3.1 Scalar and Vector Quantities

- Differentiate between scalar and vector quantities.

3.2 Speed, Velocity and Acceleration

- Understand the difference between distance and displacement

  and speed and velocity.

- Distinguish between average speed and average velocity.

- Define acceleration.

- Interpret graphs of position versus time to determine the

  velocity of an object.

- Determine from a graph of velocity versus time, the velocity of

  an object at a given time and the time at which an object has a

  specific velocity.

- Calculate the displacement of an object from the area under

  a v-t curve.

- Use the kinematics equations to solve problems for an object

  moving with a constant acceleration along a straight line.

3.3 Free-Fall

- Recognize the meaning of the acceleration due to gravity.

- Use the motion equations to solve problems involving freely

  falling objects.

3.4 Projectile Motion

- Recognize that the vertical and horizontal motions of a projectile

  are independent.

- Solve problems involving projectile motion for projectiles fired

  horizontally.
