Ch-02: Kinematics

Ch-02: Kinematics

After studying this unit, the students will be able to:

• Describe using examples how objects can be at rest and in motion simultaneously.
• Identify different types of motion i.e translatory (linear random and circular); rotatory and vibratory motions and distinguish among them.
• Differentiate with examples between distance and displacement, speed and velocity.
• Differentiate with examples between scalar and vector quantities.
• Represent vector quantities by drawing.
• Define the terms speed, velocity and acceleration.
• Plot and interpret distance-time graph and speed-time graph.
• Determine and interpret the slope of distance-time and speed-time graph.
• Calculate the area under speed-time graph to determine the distance travelled by the moving body.
• Derive equations of motion for a body moving with uniform acceleration in a straight line using graph.
• Solve problems related to uniformly accelerated motion using appropriate equations.
• Solve problems related to freely falling bodies using 10ms-2 as the acceleration due to gravity.
