Accepted Answer

### Question 1
# Brief Explanations:
Displacement is defined as the distance and direction of an object's change in position from the starting point. Distance is just the total path length, motion is the change in position, and a reference point is for comparison. So the correct option is a.
# Answer:
a) displacement

### Question 2
# Brief Explanations:
When Jermaine runs 2 laps around a 400 - meter track, he starts and ends at the same point. Displacement is the change in position from start to end, so if start and end are the same, displacement is 0.
# Answer:
c) 0

### Question 3
# Brief Explanations:
Distance is the total path length. Bill runs 400 meters to Andy's house and then 400 meters back. So total distance is $400 + 400=800$ meters.
# Answer:
a) 800 meters

### Question 4
# Brief Explanations:
To find total distance, we add the distance from home to school and school to park. From the diagram, home to school is 5 km and school to park is 3 km. So total distance is $5 + 3 = 8$ km.
# Answer:
b) 8 km

### Question 5
# Brief Explanations:
Displacement is the straight - line distance and direction from start (home) to end (park). From the diagram, home to park is 2 km east.
# Answer:
c) 2 km E

### Question 6
# Brief Explanations:
The person walks 50 meters north and then 32 meters south. The net displacement is $50-32 = 18$ meters north (since north is positive and south is negative, and 50>32, the direction is north).
# Answer:
d) 18 meters N

### Question 7
# Brief Explanations:
A frame of reference is a place or object used for comparison to determine if another object is in motion. Point of view is a perspective, comparison point is not the correct term, and motion detector is a device to detect motion.
# Answer:
a) frame of reference

### Question 8
# Brief Explanations:
The unit for distance is meter (m). Second (s) is for time, m/s is for speed, and gram (g) is for mass.
# Answer:
c) m

### Question 9
# Brief Explanations:
After a roller coaster completes one trip, it starts and ends at the same point. Displacement is the change in position from start to end, so displacement is zero. Reference point is for comparison, length is a measure of size, and distance is the total path length (which is not zero here).
# Answer:
d) displacement

### Question 10
# Brief Explanations:
Stationary (not moving) reference points are the best because if the reference point is moving, it becomes difficult to accurately determine the motion of the object being observed. So the statement is true.
# Answer:
b) true
