Chapter 2: One-Dimensional Kinematics

Velocity

Indicates both how fast an object is moving and in what direction.

Instantaneous velocity (2D Kinematics)

Instantaneous speed

The magnitude of instantaneous velocity.

Instantaneous speed (2D Kinematics)

Instantaneous acceleration (2D Kinematics)

Displacement

The net difference in the location of an object independent of how the object got there.

Average quantities

These are often denoted as the variable with a bar over it (v, a)

Derivation of Average Velocity

Derivation of Average Speed

Total Distance

The distance traveled irrespective of direction

vectors

Velocities and displacements are \__________

scalars

speeds and distances are \_________

Derivation of Average Acceleration

fundamental schematic

positive curvature

Positive acceleration corresponds to \____________

negative curvature

Negative acceleration corresponds to \_________

Non Uniform accelerated motion problems

These generally involve conversion between position, velocity, and acceleration via differentiation or integration .

UAM problems

These problems give you a set of values (such as x0, v0, a, t1, and t2) and ask you to calculate other values from them.
