The Law of Conservation of Energy.
What is The Law of Conservation of Energy states that energy cannot be created or destroyed; it can only change form?
Ramp
What is Inclined Plane?
Name all of the simple machines.
What is lever, inclined plane, wheel and axle, wedge, pulley, and screw?
Size of gear in a gear system that has greater speed.
What is the smaller gear?
A force.
What is a push or a pull?
The Law of the Conservation of Mass.
What is The Law of Conservation of Mass states that mass cannot be created or destroyed; it can only change forms?
Change in position due to an applied force.
What is work?
Simple machine on which the wedge and screw are based.
What is Inclined Plane?
How mechanical advantage is paid for in most simple machines?
What is the force must be applied over a longer distance?
A force that resists motion.
The six simple machines.
What is The six simple machines are the lever, inclined plane, wheel and axle, wedge, pulley, and screw. All of the simple machines are based on two of these: the lever and the inclined plane?
The ability to perform work.
What is Energy?
The mechanical advantage of a 3 pulley system
What is 3?
Who is doing more work? Student A who picks up a feather or Student B who is pushing with all his might on a wall?
Who is Student A because there needs to be a change in position in order for work to be done?
A continuous pull on an object.
What is tension?
Different Classes of Levers
What is
There are three classes of levers.
In a first-class lever, the fulcrum is in the middle — like a seesaw.
In a second-class lever, the load is in the middle — like a wheelbarrow.
In a third-class lever, the effort is in the middle — like a baseball bat or your arm.
F-L-E— Fulcrum, Load, Effort!
The study of motion.
What is mechanics?
Simple Machine on which the wheel & axle and pulley are based.
Give an example of kinetic energy.
What is {something in motion}?
The sum of all of the forces on an object.
What is net force?
Newton's First Law of Motion.
What is Newton’s first law of motion states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force. This is also called the law of inertia?
Ability to move an object using less force.
What is mechanical advantage?
The size gear that exerts a greater force.
What is the larger gear?
Give an example of potential energy.
What is {energy that's being stored?}
A force that is exerted by liquids and gases.
What is buoyancy?
