RIO SALADO PHY 111 FINAL EXAM 2026
EXAMS SET QUESTIONS AND COMPLETE
SOLUTIONS DETAILED PRACTICE
COMPILATION GRADED A+
⩥ Velocity.
Answer: Speed of a moving object in a particular direction.
⩥ Acceleration.
Answer: any change in the velocity of the object with respect to time
⩥ T or F: If something always has a constant speed then it can still
accelerate.
Answer: True, "still" is the key word
⩥ T or F: A hammer hit a nail on a block of wood. If the nail does not go
into the wood then the force of the hammer on the nail is less than the
nail's force on the hammer..
Answer: False, the forces are equal due to Newton's 3rd Law.
⩥ T or F: It is possible to accelerate towards a certain point in space but
to never actually get there..
, Answer: True, Circle
⩥ T or F: While standing still on a slope, your weight is cancelled by the
normal force..
Answer: False, there is your normal force pushing straight down and a
vector pointing down the slope.
⩥ T or F: The D=Vt equation is only valid if acceleration is constant..
Answer: False, a=0 in order to be canceled out of the equation.
⩥ What are the units of weight and inertia?.
Answer: Weight= N
Inertia= Kg
⩥ T or F: Because of the t-squared, x=xo+vot+(1/2)at^2 is valid if a
changes in time.
Answer: False, change in a=0 only.
⩥ T or F: It is reasonable to add force vectors to acceleration vectors
only if they are perpendicular..
Answer: False, must be the same type of force vector.
