Reduces the amount of force, changes the distance of the force applied or changes the direction of the force applied.
What are Simple Machines?
100
Distance / Time
What is Speed?
100
This is a push or a pull, it can be balanced or unbalanced. It is measured in Newtons.
What is a force?
100
The tendency of an object to resist a change in direction.
The amount of resistance depends on the mass of the object.
More mass = more resistance.
What is inertia?
100
This measures the amount or quantity if matter in an object.
What is mass?
200
A rope threaded through a wheel or a disk.
What is a pulley?
200
A measure of an object's change in position per unit of time and it's direction of motion.
What is Velocity?
200
A force that acts to resist sliding between two objects. It can be increased or reduced.
What is friction?
200
Newtons Third Law as it relates to a basketball.
What is dribbling a basketball?
200
The tip of a dart.
What is a wedge?
300
An plane that pivots or rotates around a center point called a fulcrum.
What is a lever?
300
The measure of how quickly velocity changes.
Example: A car speeds up.
What is acceleration?
300
The net force on an object at rest is zero, the object will remain at rest, or if the object is moving it will continue to move at a constant speed and in a straight line.
What is Newtons First Law?
300
How a ball rolled on a long level street with no bumps or objects to bump into begins to decelerate and eventually comes to a stop.
What is friction?
300
Why astronauts weigh less in outer space.
What is lack or absence of the Earth's gravity.
400
This represents the ratio of energy output to the energy input.
What is efficiency?
400
The amount of matter in an object. It remains constant and is measured in kilograms.
What is mass?
400
Represented as f=ma where f = force, m = mass and a = acceleration; this states that an object acted upon by a force will accelerate in the direction of the force.
What is Newton's Second Law of Motion.
400
This is measured in Newtons.
What is force?
400
A bicycle.
What is a complex or compound machine?
500
The ratio of the distance over which the force is applied to the distance over wich a load is moved.
What is mechanical advantage?
500
The mass of an object times its velocity. It is represented by the following equation: p = m/v
What is Momentum?
500
For every action there is an equal and opposite reaction.
What is Newtons Third Law of Motion.
500
An object at rest on a table is acted upon by 10 newtons of force applied towards the left. The object falls off the table on the left side.
