motion

Question 1

difference between speed and velocity

Answer 1

Speed is the rate of distance covered and is scalar, while velocity is the rate of displacement in a specific direction and is vector.

Question 2

formmula of accelaration

Answer 2

a = v0 - v1 /t

Question 3

What is the quantity which is
measured by the area occupied
below the velocity-time graph?

Answer 3

Displacement

Question 4

below its line

Answer 4

displacement

Question 5

speed time graph givees

Answer 5

distance

Question 6

final velocity[v] =

Answer 6

u + at

Question 7

s=

Answer 7

s=ut+1/2 * at^2

Question 7

v2-u2=

Answer 7

v2-u2= 2as

Question 8

Distance:

Answer 8

It is the total length of the path traveled by an object, regardless of direction.

Scalar quantity (has only magnitude, not direction).
Always positive and cannot be zero if there’s any movement.

Example: If you walk 10 meters forward and 10 meters back, the distance is 20 meters.

Question 9

Displacement

Answer 9

It is the shortest straight-line distance between the starting and ending points.
Vector quantity (has both magnitude and direction).
Can be zero if the start and end points are the same.
Example: If you walk 10 meters forward and then 10 meters back to the starting point, displacement is 0 meters.

Question 10

1. Which of the following statements is true about displacement?

A) It is always equal to or less than distance.
B) It only considers the path traveled by an object.
C) It is a scalar quantity.
D) It is always positive.

Answer 10

A) It is always equal to or less than distance.

Question 11

2. An athlete runs around a circular track with a radius of 50 meters. After completing one full lap, what is the displacement?

A) 100 meters
B) 314 meters
C) 0 meters
D) 157 meters

Answer 11

0

Question 12

6. Which of the following best describes the relationship between distance and displacement?

A) Distance is always greater than displacement.
B) Distance is equal to displacement in a straight-line motion with no change in direction.
C) Distance and displacement are always the same for any journey.
D) Displacement is always greater than distance.

Answer 12

Distance is equal to displacement in a straight-line motion with no change in direction.

Question 15

If an object moves at a constant speed along a circular path, what can be said about its velocity?

Answer 15

Correct Answer: C) It does not have a constant velocity because the direction changes continuously
