Question 1

Define motion

Answer 1

Something changing its position

Question 2

What elements make motion

Answer 2

position and time

Question 3

what is distance

Answer 3

The measure of how far an object has moved

Question 4

What is displacement

Answer 4

displacement specifies the distance and direction, less realistic

Question 5

what is speed

Answer 5

speed is how quickly an object is moving

Question 6

What is the equation for speed

Answer 6

change of position/ time

Question 7

is speed measured at scalar or vector

Answer 7

Scalar

Question 8

in letters what is the equation for speed

Answer 8

v=s/t s= distance t=time

Question 9

What is velocity

Answer 9

Velocity is speed with a directional property e.g 20/s left to right

Question 10

In letters what is the velocity equation

Answer 10

same as speed with arrows on top of the v and s

Question 11

What is scalar

Answer 11

One metric measurement e.g magnitude

Question 12

what is vector

Answer 12

two pieces of information eg. magnitude and direction

Question 13

What is average speed

Answer 13

can be calculated by finding the total distance travelled and dividing this by time taken

Question 14

what is instantaneous speed

Answer 14

refers to the speed that an object is travelling at a particular time

Question 15

Equation for acceleration

Answer 15

Change of speed/ time taken

Question 16

Definition of acceleration

Answer 16

When an object starts travelling faster

Question 17

A runner accelerates from a standing start to a speed of 12m/s after 2nds what is his acceleration

Answer 17

12-0/2=6m/s

Question 18

What does meters per second look like

Answer 18

M/S^2 or m.s^_2
