Presentation Transcript

### Chapter 2: Motion in One Dimension

• Motion along a straight line

• Motion

• Position and Displacement

• Average velocity and average speed

• Instantaneous velocity and speed

• Acceleration

• Constant acceleration: A special case

• Free fall acceleration

Displacement is a vector quantity. It has both a direction and magnitude!

Motion Along a Straight Line

• Everything moves!

• Classification and comparison of motion  kinematics

• Simplification

• Motion along straight line

• Forces cause motion

• Moving object is a particle or moves like a particle

Displacement

• Average velocity

• Average speed

• Instantaneous velocity

Instantaneous acceleration

Constant acceleration

Acceleration

An elevator is initially stationary, then moves upward (which we take the positive direction of x), and then stops. Plot v as a function of time.

• x(t) curve for an upward moving elevator cab

• v(t) curve for the cab. Note v = dx/dt!

• a(t) curve for the cab. Note a =dv/dt!

• Integration of acceleration

• Indefinite integral or anti–derivative

• Constant of integration
