Topic 2: Mechanics

2.1. Kinematics

2.1.1. Define displacement, velocity, speed, and acceleration. • Displacement (a vector quantity) is a measured distance in a given direction in ([pic]). • Speed (a scalar quantity) is the rate at which a moving object covers distance in ([pic]). • Velocity (a vector quantity) is speed in a given direction (in [pic]). • Acceleration (a vector quantity) is the rate of change of velocity in a given direction (in [pic]). 2.1.2. Explain the difference between instantaneous and average values of speed, velocity and acceleration. • Average velocity: [pic] the change in displacement divided by the change in time. The slope of the secant line of a displacement-time graph over a given interval. • Instantaneous velocity: [pic] the … as the change in time becomes infinitely small. The derivative of the displacement-time graph function at a given point. • Speed and acceleration work in similar ways.

2.1.3. Outline the conditions under which the equations for uniformly accelerated motion may be applied. • Objects must be uniformly accelerated.
• Objects must be in linear motion (traveling in a straight line). 2.1.4. Identify the acceleration of a body falling in a vacuum near the Earth’s surface with the acceleration g of free fall. • Constant acceleration at [pic].
