1. Overview

Try these first

1. 1.

   What is displacement in kinematics?

   Hint

   Think about what happens when an object moves.

2. 2.

   Describe how velocity differs from speed.

   Hint

   Consider a car moving north at 60 km/h.

3. 3.

   What does kinematic analysis not consider?

   • Forces
   • Positions
   • Velocities

   Hint

   Focus on what aspect of motion is analyzed.

4. 4.

   True or False: Acceleration includes both tangential and centripetal components.

   • True
   • False

   Hint

   Reflect on the definitions of acceleration.

5. 5.

   A car travels in a circular path of radius 50 m at a speed of 10 m/s. Calculate its centripetal acceleration.

   Hint

   Remember the formula for centripetal acceleration involves radius.

6. 6.

   In a four-bar linkage, the lengths of the links are 2 m, 4 m, and 3 m respectively. Find the positions using the loop closure equation.

   Hint

   Use geometry to visualize the closed loop of the linkage.
