Answer 4

kinematics

Question 4

It has only the magnitude

Only one dimensional

Answer 4

SCALAR

Question 5

This quantity changes with the change in magnitude

Answer 5

SCALAR

Question 6

It has direction and magnitude

Answer 6

VECTOR

Question 7

It is multidimensional
This changes with magnitude and direction

Answer 7

VECTOR

Question 8

The complete length of the length between any two path between any two points points when measured along is called —-

Answer 8

DISTANCE

Question 9

Distance can have negative and positive values

T OR F

Answer 9

false

just positive

Question 10

distance is a vector quantity

T OR F

Answer 10

FALSE

Distance is a scalar quantity as it only depends upon the magnitude and not the direction

Question 11

is the direct length between any two points when measured along the minimum path between them

Answer 11

DISPLACEMENT

Question 12

Displacement is a vector quantity as it depends upon both

T OR F

Answer 12

TRUE

Question 13

Displacement can only be positive

t or f

Answer 13

false

can be positive, negative and even zero

Question 14

is a scalar quantity which means it has no direction. It denotes how fast an object is moving.

Answer 14

Speed

Question 15

the rate of distance traveled by a moving object over time

Answer 15

speed

Question 16

the rate of displacement of a moving object over time

Answer 16

velocity

Question 16

is a vector quantity which means it has both magnitude and direction. It denotes the rate at which the object is moving or changing position.

Answer 16

VELOCITY

Question 17

is defined as the change in the velocity of an object with respect to time

Answer 17

Acceleration

Question 18

can be defined as a scenario when an object is moving only under the effect of the Earth’s gravitational pull.

Answer 18

Freefall

Question 19

As external force is exerted on the object, the motion will be constantly accelerated. This is known as ——-

Answer 19

freefall acceleration.

Question 20

In a —–, there are two simultaneous independent rectilinear motions:

Answer 20

Projectile Motion

Question 21

uniform velocity, responsible for the horizontal (forward) motion of the particle

Answer 21

Projectile motion - Along the x-axis:

Question 22

uniform acceleration, responsible for the vertical (downwards) motion of the particle.

Answer 22

Projectile motion - Along the y-axis:

Question 23

the pathway followed by an object in projectile motion is

Answer 23

trajectory

Question 24

The horizontal distance traveled in projectile motion is known as the —-.

Answer 24

range

Question 25

the highest point reached is called the —– in projectile motion.

Answer 25

maximum height

Question 26

In projectile motion, Vertical velocity remains constant. Horizontal velocity changes continuously.

true or false

Answer 26

false

Horizontal velocity remains constant.Vertical velocity changes continuously.

Question 27

true or false

in projectile motion, horizontal speed decreases as the object ascends and increases as it descends

Answer 27

FALSE

Vertical speed decreases as the object ascends and increases as it descends.

Question 28

Projectile motion can occur at different angles.

true or false

Answer 28

true
