Definition of Terms

Question 1

It is concerned with the motion of the objects without reference to the force that caused the motion

Answer 1

Kinematics

Question 2

This is the scalar quantity which refers to how much ground an object has covered while in motion

Answer 2

Distance

Question 3

This is a vector quantity concerned with how far the object is from its starting to end point

Answer 3

Displacement

Question 4

This is a scalar quantity which refers to how fast one is moving

Answer 4

Speed

Question 5

A vector quantity which refers to how fast one moved from its starting and end point

Answer 5

Velocity

Question 6

It is distance over time

Answer 6

Speed

Question 7

It is displacement over time, rather

Answer 7

Velocity

Question 8

The vector quantity which defines the change in an object’s velocity

Answer 8

Acceleration

Question 9

What does the direction of acceleration depend on?

Answer 9

It depends whether the object is accelerating or decelerating

Question 10

(Position v Time Graph)

What happens when the plot of the graph goes up?

Answer 10

It has constant speed or velocity.

It has zero acceleration.

Question 11

(Position v Time Graph)

What happens when the plot of the graph is a straight line?

Answer 11

There is no velocity or speed present.

The object is at rest.

Question 12

(Position v Time Graph)

What happens when the graph is an upward curve going to the right?

Answer 12

There is changing speed or velocity.

Question 13

(Velocity v Time Graph)

What happens when the plot of the graph goes up?

Answer 13

There is constant acceleration. (Thus, the velocity changes.)

Question 14

(Velocity v Time Graph)

What happens when the plot of the graph is a straight line?

Answer 14

There is zero acceleration. (Thus, the velocity is constant.)

Question 15

(Velocity v Time Graph)

What happens when the graph is an upward curve going to the right?

Answer 15

There is a none uniformed acceleration.

Question 16

(Position v Time)

This is the axis with the values of time on it.

Answer 16

X-Axis

Question 17

(Position v Time)

This is the axis with the values of the position on it.

Answer 17

Y-Axis

Question 18

(Position v Time)

This indicates the velocity of the objects which is tentative due to the quantity.

Answer 18

Slope of the Line

Question 19

This is known as equal displacements which occur during successive equal intervals of time (Straight lines on the position v time graphs mean this.)

Answer 19

Uniform Motion

Question 20

(Position v Time)

1. Steep slope = ?
2. Shallow slope = ?

Answer 20

1. Higher velocity

2. Less velocity

Question 21

(Velocity v Time)

This is the axis with the values of time on it.

Answer 21

X-Axis

Question 22

(Velocity v Time)

This is the axis with the values of velocity on it.

Answer 22

Y-Axis

Question 23

This is the representation of acceleration in a velocity v time graph.

Answer 23

Slope of a Line

Question 24

This is known as equal intervals added to the velocity which occurs during successive equal time periods (Straight lines on the velocity v time graphs mean this.)

Answer 24

Uniformly Accelerated Motion

Question 25

In what kind of situations do we use the Big Four formula?

Answer 25

1. When the displacement is not mentioned.
2. When the acceleration is not mentioned.
3. When the final velocity is not mentioned.
4. When the time is not mentioned.

Question 26

This is in the indicated motion where the resistance of air is neglected and acceleration is shown to be constant. And the only force acting upon it is gravity.

Answer 26

Free fall

We’re just ordinary free-fall
