Linear Motion

Question 1

Linear Motion Definition

Answer 1

Motion in a straight line with all body parts moving at the same distance in the same direction. Results from a direct force being applied to the center of the object’s mass

Question 2

Linear Motion Key Descriptors

Answer 2

Distance, Displacement, Velocity, Speed, Acceleration, Deceleration

Question 3

Linear Motion Measurements

Answer 3

Scalar and Vector Quantities

Question 4

Scalar Quantities Definition

Answer 4

Described in terms of Size or Magnitude

Question 5

Scalar Quantities

Answer 5

Mass, Inertia, Distance, and Speed

Question 6

Vector Quantities Definition

Answer 6

Described in terms of size and direction

Question 7

Vector Quantities

Answer 7

Weight, acceleration, deceleration, displacement, momentum, velocity

Question 8

Distance and Displacement

Answer 8

• Vector Quantities

- Describe the body’s motion

Question 9

Distance Definition

Answer 9

The length of the path a body follows when moving to a point

ex. 400m Runner

Question 10

Displacement Definition

Answer 10

The length of a straight line joining the start and finish points
ex. 200m race on a track, the displacement will be the number of meters from start to finish (across the field)

Question 11

Speed Definition

Answer 11

• Scalar quantity (does not consider direction)
• The rate of change of position
• Speed= Distance covered/ time taken (s)

Question 12

Velocity

Answer 12

• Vector Quantity
• The rate of change of position with reference to the direction
• Velocity=Displacement/Time Taken

Question 13

Acceleration and Deceleration

Answer 13

• Vector Quantities

- The rate of change of velocity

Question 14

Velocity and Deceleration and Acceleration

Answer 14

Acceleration occurs when velocity increase

Deceleration occurs when velocity decreases
