already passed 2026/2027
π - correct answer ✔3.14
Expression for speed - correct answer ✔s=d/t
expression for acceleration - correct answer ✔a=Δv/t
expression for velocity - correct answer ✔v= Vo+at
expression for distance - correct answer ✔Vot+1/2at²
expression for force - correct answer ✔Fnet=ma
expression for weight - correct answer ✔w=mg
1cm = - correct answer ✔10mm
1in = - correct answer ✔2.54cm
1m= - correct answer ✔100cm
1 mi = - correct answer ✔1609.344m
, 1l - correct answer ✔1000cc
speed - correct answer ✔is how fast something is moving.
Average speed - correct answer ✔total distance divided by total time
Instantaneous speed - correct answer ✔is the speed at that precise instant in time. EX -SPEEDOMETER
Velocity - correct answer ✔involves direction of motion as well as how fast the object is going
Acceleration - correct answer ✔is the rate at which velocity changes.
can be either a change in the object's speed or direction of motion
average acceleration - correct answer ✔the change in velocity divided by the time required to
produce that change.
EXPRESSION FOR TIME - correct answer ✔T=D/S
what is the difference between speed and velocity - correct answer ✔speed tells how fast something
is moving, but does not tell the direction, velocity tells both direction and speed of object (vector)
gravity - correct answer ✔9.8
A student releases a ball from rest on an inclined plane and measures that it travels a distance of 0.5 m
in a time of 2.0 s. The average speed of the ball is
