Chapter 9 Motion

Question 1

How to calculate speed

Answer 1

Speed(m/s)=d(m) / time(s)

Question 2

How to find distance

Answer 2

Distance(m)=speed(m/s) x time(s)

Question 3

How to find time

Answer 3

Time(s)= distance(m) / speed(m/s)

Question 4

What is accelerarion(formula) aswell

Answer 4

Accelerstion of an object is its change of velocity per second

Acceleration(m/s^2) = change in velocity(m/s) / time taken for the change(s)

Question 5

What is decleration

Answer 5

Used for when an object slows down

Question 6

How to calculate distance travelled

Answer 6

Find the area
Usually a shape like triangle or square

Question 7

How to find gradient of straight line

Answer 7

Gradient of line = height of triangle / base of triangle

Question 8

How to find gradient of curved line at a certain point

Answer 8

First draw a tangent to the curve then draw suitable triangle with good values to work with then then find gradient of line
