Work or not? push on a stationary wall
What is NOT work
Which is MORE work:
4N going 2m OR 2N going 3m
What is 4N going 2 m?
Any device that makes work easier by changing the direction or amount of force to accomplish a task.
What is a simple machine?
This is a double inclined plane that moves.
What is a wedge
The mechanical advantage of a lever lifting a 50N rock with 5 N of force
What is 10?
The work done If a 5N box moves 3m with a push.
What is 15J?
Work done to a 6 N box moving up a 2 m ramp.
What is the 12J?
This is a bar, beam, stick, or rod and a fulcrum or pivot point.
What is a lever?
This is a simple machine that consists of a rope that fits into a groove in a wheel.
What is a pulley
A person's force moves one side of a lever 4 meters so that the box on the other end moves 2 meters. What is MA?
What is 2?
In order to do work on an object, this must be in the same direction as the object moves
What is the force?
The force applied if the work of the machine is 10 J and it moves 5 m.
What is 2N?
Machine these are examples of: dolly to move a box, car, bike
What is a wheel and axle?
An axe is an example of this simple machine.
What is a wedge?
What is MA if the radius of the wheel is 30 cm and the radius of the axle is 10 cm.
What is 3?
An inclined plane increases the distance which decreases the_______ needed for work to be done.
What is the force?
Name a way that machines make doing work easier
What is increasing force, changing force and distance, and changing the direction of a force
What is 50?
