Simple Machines
A simple machine that consists of a sloping surface and makes it easier to lift heavy objects.
What is inclined plane?
The formula for work is this.
What is work = force × distance?
This is the formula for force, as described by Newton’s Second Law.
What is force = mass × acceleration?
This simple machine is a flat object that pivots around a fixed point.
What is a lever?
The wedge is used to do this to an object.
What is split, cut, or hold?
A wheel attached to a rod or shaft that is used to lift or move loads.
What is a wheel and axle?
Work is only done when this happens to the object.
What is the object moves in the direction of the force?
The unit of force in the metric system.
What is the newton?
This simple machine combines two or more wheels and axles to create a powerful tool, such as in a clock.
What is a gear?
This simple machine is found in tools like jar lids, bolts, and spiral staircases.
What is a screw?
The mechanical advantage of a lever depends on the location of this point.
What is a fulcrum?
If a 10 N force moves an object 5 meters, how much work is done?
What is 50 joules?
The opposing force that resists the motion of objects sliding past one another.
What is friction?
This machine uses a combination of ropes and pulleys to lift very heavy objects.
What is a block and tackle?
This is the main advantage of using a simple machine.
What is reducing the amount of force needed?
This type of simple machine includes a grooved wheel with a rope wrapped around it.
What is a pulley?
The unit of power, named after a famous inventor.
What is the watt?
The force of gravity acting on an object is known as this.
What is gravity?
The length of the inclined plane divided by its height gives this mechanical property.
What is mechanical advantage?
Which type of lever has the fulcrum in the middle, like a seesaw?
What is a first-class lever?
A screw is a modified version of this simple machine.
What is an inclined plane?
Power measures how fast this is done.
What is work?
If a 50 kg object accelerates at 2 m/s², the net force acting on it is this.
What is 100 N?
Name one example of a third-class lever.
What is a baseball bat, fishing rod, or tweezers?
This simple machine often works in combination with an inclined plane to make moving objects easier.
What is a wheel and axle?
