3. Linear Motion: Terms & Definitions

Question 1

Angular Motion

Answer 1

A change in orientation, rotation around a fixed axis

Question 2

Axis of Rotation

Answer 2

The axis of rotation is an imaginary line around which an object rotates, with all points on the object moving in circular paths centered on this line

Question 3

Curvilinear Motion

Answer 3

Curvilinear motion is the movement of an object along a curved path, where the direction of motion continuously changes but the object follows a smooth trajectory.

Question 4

Displacement

Answer 4

Change in Position from starting point to ending point

Vector

Question 5

Distance

Answer 5

Total amount travelled

Scalar

Question 6

Dynamic State

Answer 6

Dynamic state refers to a condition in which an object is in motion, experiencing changes in velocity or direction due to unbalanced forces.

Question 7

General Motion

Answer 7

Combined linear and angular motion

Question 8

Linear Kinematics

Answer 8

Linear Kinematics

Question 9

Linear Motion

Answer 9

Linear motion is the movement of an object along a straight line, where all parts of the object move in the same direction and cover the same distance.

Question 10

Motion

Answer 10

Motion is the change in position of an object over time relative to a reference point.

Question 11

Pace

Answer 11

Pace is the rate or speed at which an activity, such as walking or running, is performed, typically measured in time per unit of distance.

Question 12

Rectilinear Motion

Answer 12

Rectilinear motion is the movement of an object along a straight line, where the direction and path remain consistent throughout the motion.

Question 13

Rotation

Answer 13

Rotation is the circular movement of an object around a central point or axis, where all parts of the object follow a circular path.

Question 14

Scalar

Answer 14

A scalar is a quantity that has only magnitude and no direction, such as mass, temperature, or time.

Question 15

Speed

Answer 15

Speed is the rate at which an object covers distance, defined as the total distance traveled divided by the time taken, without considering direction.

Question 16

Static State

Answer 16

Static state refers to a condition in which an object remains at rest, with no movement or changes in velocity, due to balanced forces acting on it.

Question 17

Translation

Answer 17

Translation is the movement of an object in which all parts move in the same direction and distance, without any rotation or deformation.

Question 18

Vector

Answer 18

A vector is a quantity that has both magnitude and direction, commonly used to represent physical concepts like force, velocity, or displacement.

Question 19

Velocity

Answer 19

Velocity is the rate of change of an object’s displacement in a specific direction, making it a vector quantity that includes both speed and direction.
