PHYSICS LAB EXAM 1 | QUESTIONS WITH VERIFIED
ACCURATE ANSWERS | 2026
What was the purpose of intro to motion lab - Answers - use motion detector to create
velocity-time and acceleration-time graphs. to do so, you walk holding a board.
Kinematics - Answers - study of motion and its mathematical and graphical
representation
distance time graphs - Answers - walk away- increasing; walk towards- decreasing. the
two produce opposite slopes. you can make a curved one by changing speeds slowly.
velocity-time graphs - Answers - walk towards- negative straight squiggly line. walk
away- positive straight squiggly line. when you move slower, the osculations occur less
frequently and vice versa. a straight line means constant velocity
does a velocity graph tell you where to start? - Answers - no, it tells you how much you
move; not where you began.
how can you tell from a velocity time graph that the moving object has changed
direction? what is the velocity the moment it changes? - Answers - the value either
becomes positive or negative. when it changes, V=0
what is the purpose to changing motion lab - Answers - to understand acceleration and
calculate the average acceleration. to do so, you use a face on a friction less surface
acceleration time graphs - Answers - if the slope of velocity is negative, the acceleration
is negative. if speeding up, the slope is positive and if slowing dow, the slope is negative
how do you know based on signs one is slowing down - Answers - when you have two
points with opposite signs, you are slowing down. at the turning point, V=0 and
acceleration is always negative.
how do you find average acceleration - Answers - change in velocity/ change in time
how can you tell the sign of the acceleration from an acceleration-time graph - Answers
- by looking at the slope
when something is slowing down, what sign is the acceleration - Answers - negative
what was the purpose of force and motion lab - Answers - learn how to measure force,
explore relationships between force and acceleration.
