Physics 121 Midterm 1 Question and
answers verified to pass 2025
What's the difference between scalar and vector? - correct answer ✔Scalar
is a numerical values while a vector possesses both magnitude and direction.
position distance and displacement? - correct answer ✔location of an object
on a coordinate system, total length of travel, change in position
instantaneous velocity - correct answer ✔how fast a particle is moving in a
moment in time
what does the slope equal on a position (x) vs time (t) graph? - correct
answer ✔m = velocity
what does the slope equal on a velocity (v) vs time (t) graph? - correct
answer ✔m = acceleration
when acceleration is constant... - correct answer ✔instantaneous and
average acceleration are equal
freely falling objects - correct answer ✔motion of object is only subject to the
influence of gravity, which is a constant variable on earth
initial velocity and position is 0
vector component - correct answer ✔measure of how much it extends in
certain direction
