Graphs And Stuff Flashcards
What are forces measured with
Newtonmetres
What must all measurements have
A unit
What happens if forces are not equal
They are unbalanced and the speed of the object changes
What happens if forces are balanced
They move at a steady speed or stay still
What forces occur on a hanging object.
Weight and tension
What forces occur on a floating object
Weight and Upthrust
What forces occur on a toy car on a ramp
Weight and reaction
What forces occur on falling paper
Weight and air resistance
What forces occur on a magnet and paper clip
Weight and magnetic attraction
What forces occur on two masses on a pulley
Weight and Tension
How would you calculate the average speed
Distanced travelled divided by the mean time taken
How would you calculate the time
The distance divided by the speed
How would you calculate the distance
The speed times the time
What would a straight line on a graph show
No movement
What would a line curving up show
The speed is getting faster
What would a line curving to the right show
The speed slowing down
What is mass measured in
Kilograms
What is weight
Weight is a force
Is there different weights on different planets
Yes
Is there different mass on different planets
No
What would the weight be for a body of mass 1kg
10N
What happens to the weight of a body as it’s mass goes up
The weight goes up/ becomes heavier
The more mass you have,the more weight you have…
The earths gravity pulls harder on you.
The strength of gravity on earth is…
10N on every kg,10N per kg, 10N/ kg
