Answer 3

D/T

Question 4

A quantity that only indicates “How much” (the magnitude) of the quantity

Answer 4

Solar Quantity

Question 5

Indicates the magnitude and the direction of the quantity

Answer 5

Vector Quantity

Question 6

A solar quantity, measures the change in distance

Answer 6

Distance Travelled

Question 7

Measures the change in distance and the direction of the change in position of an object from a reference point

Answer 7

Displacement

Question 8

A scalar quantity

Answer 8

Speed

Question 9

Describes both rate of motion and direction of an object

Answer 9

Velocity

Question 10

A method for determining t = vector directions using the mathematic method of setting up a grid with an x axis and y axis like a graph. The starting point is 0 on the x-axis, and the directions are determined in a counter clockwise direction and are given in positive or negative directions

Answer 10

The X method

Question 11

UP AND RIGHT

Answer 11

Positive

Question 12

DOWN AND LEFT

Answer 12

Negative

Question 13

This method uses the direction of north, south, east and west on a grid to identify vector directions North is the starting point of 0; and directions are stated clockwise from there

Answer 13

The navigator method

Question 14

N and E

Answer 14

Positive

Question 15

S and W

Answer 15

Negative

Question 16

The most common type of motion, the change in velocity during a specific time interval

Answer 16

Acceleration

Question 17

When the change in both the magnitude of the velocity and the direction are positive

Answer 17

Positive acceleration

Question 18

When the change in both the magnitude of velocity and the direction are negative

Answer 18

Positive acceleration

Question 19

When the change in the magnitude of velocity is negative and the direction is positive

Answer 19

Negative acceleration

Question 20

When the change in the magnitude of velocity is positive and the direction is negative

Answer 20

Negative acceleration

Question 21

The ability to do work, measured in joules (j) e=w

Answer 21

Energy

Question 22

A push or pull on an object measured in newtons

Answer 22

Force

Question 23

Whenever a force moves an object through a distance that is in the direction of force, then work is being done

Answer 23

Work

Question 24

w=

Answer 24

fd

Question 25

Average velocity =

Answer 25

Displacement/time elapsed
