Summary
These notes provide a comprehensive overview of kinematics, a branch of physics focusing on motion. Concepts like displacement, velocity, and acceleration are explored, along with relevant equations and graphs. Practical applications are shown through sample problems and experimental set-up.

The area beneath a velocity-time graph is displacement, therefore: 2 2 2. The gradient of a velocity-time graph is the acceleration, therefore: 3. The area beneath a velocity-time graph is displacement, therefore: 4. The last equation can be found by substituting the equation from part 2 ( *v* = *u* + *at* ) into the equation from part 1 ( *s* = ( *u*+*v* )*t* ). 2 = *v*^2^ = 0^2^ + 2 × 9.81 × 50 ----------------------------- 1. Set up the apparatus as shown in the diagram, connecting the light gates to a data logger and as close to the electromagnet as possible. 2. The position of the lower light gate should be adjusted such that the height h is 0.75 m, measured using the metre ruler. 3. Turn on the electromagnet and attach the ball bearing. 4. Switch off the electromagnet, and note the time taken for the bearing to fall 5. Reduce h by 0.05 m by moving the lower light gate upwards and repeat the above two steps, reducing h by 0.05 m each time, down to 0.25 m. 6. Repeat the experiment twice more to find mean values of t for each value of h.
