I Fucked Your Mum last Night Flashcards
What’s the units for speed
M/s km/hr
What’s the unit for velocity
The same as speed
What’s the unit for distance
Meters, kilometers
What’s the unit for force
Newtons
How do you calculate mass
Force divided by accerlation
How do you calculate force
Mass x accerlation
Simple machines
Pulleys, wheel and Axel, wedge, inclined plane, lever, screw
How do you calculate distance
Speed x time
How do you calculate time
Distance divided by speed
How do you calculate speed
Distance divided by time
What’s class 1
Fulcrum in the middle
Load and effort on Ethier end
What’s class 2
Fulcrum at the end
Load in the middle
Effort at the end
What’s class 3
Fulcrum at the end
Effort in the middle
Load at the end
What’s a contact force
A force that results from the interaction of two objects in contact with each other
What’s a non contact force
The force is not in contact with the object but it stills effects the object
What are some contact forces
Push, pull, friction, air resistance, normal force, upthrust
What are some non contact forces
Magnetism, gravity, electrical
What can force change
An objects shape, speed and direction
Point to point camera does?
Calculates the average speed for a driver from a point to another
What does a speed camera do
Catches the instant speed
What’s interia rest
When an object at rest has the tendency to stay at rest
What’s interia motion
An object in motion the had a tendency to in motion
Examples of lever
Scissors, crowbar, wheelbarrow, fishing rod, oars
what does ma mean
Mechanical advantage
How do you calculate mechanical advantage
Effort arm dived by load arm
What does having a longer effort arm mean?
It’s more effective
Difference between speed and velocity
Velocity has mangtiude with direction
What’s mass
Matter contained in a object
