CPPS Exam Review GRADED A+ (ACTUAL EXAM ) Questions and Answers (Solved)
- When is an object in motion?
Answer: An object is in motion if its position changes when compared to another
object.
- the place or object used for comparison to determine whether something is in
motion.
Answer: Reference point
- A push or a pull
Answer: force
- What is force described by?
Answer: strength and direction
- Measured in Newtons (N).
Answer: force/weight
- the type of force that is applied when one object actually touches another object
Answer: Contact force
7. Ex: Friction
Answer: Contact force
- the force that 2 objects apply to each other when they rub against each other
Answer: Contact force
- a force applied to an object whether it touches the object or not.
Answer: Noncontact force
10. Ex: Gravity/magnetism
Answer: Noncontact force
- a force that pulls objects toward each other as a result of their masses.
Answer: - Gravity
- when two forces acting on an object are equal in strength & in opposite
directions. 1 / 3
Answer: Balanced force
- when two forces acting on an object are in opposite directions but NOT equal in
strength.
Answer: Unbalanced force
- the combination of all the forces acting on an object.
Answer: Net force
- Forces in the same direction are . Forces in opposite
directions are . This is called
Answer:
added subtracted Net force
- the distance an object travels in a given unit of time
Answer: Speed
- Distance/time
Answer: speed
- meters/second, kilometers/hour
Answer: speed
- the speed of an object at 1 particular instant.
Answer: Instantaneous speed
- the total distance traveled divided by the time.
Answer: speed
- objects travel at the same speed the entire time they're in
motion.
Answer: don't
- Time goes on the axis.
Answer: X
- Distance/speed goes on the axis.
Answer: Y
- / 3
- the angle of the graphed line.
Answer: Slope
- The slope represents the .
Answer: speed
- The steeper the slope, the the speed.
Answer: faster
- A constant slope/the slope stays in the same direction =
Answer: constant speed.
- the speed at which an object travels in a given direction
Answer: Velocity
- the rate at which velocity changes.
Answer: Acceleration
30. An object accelerates if:
Answer:
It speeds up It slows down It changes direction
- An object slowing down =
Answer: negative acceleration.
- Is deceleration written as a positive or negative number?
Answer: Negative
- final speed-initial speed/time
Answer: formula for acceleration
- m/s2 or km/hr2
Answer: units for acceleration
- Time is in acceleration
Answer: squared
- / 3
