The position-time graph below represents the motion of two speed skaters, Bill and Ted on their Excellent Adventure as they time travel back to the 1952 winter Olympics in Oslo. a) What was Ted’s velocity at 20s? b) What was Bill’s velocity during the middle portion of the race? c) What was Ted’s average velocity throughout the race?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
Based on a grade 11 physics student, answer the following question:
The position-time graph below represents the motion of two speed skaters, Bill and Ted on their Excellent Adventure as they time travel back to the 1952 winter Olympics in Oslo.
a) What was Ted’s velocity at 20s?
b) What was Bill’s velocity during the middle portion of the race?
c) What was Ted’s average velocity throughout the race?
d) What was Ted’s acceleration through the race? (assume constant)
e) Make a velocity-time graph of Bill & Ted’s Speed Skating race.
