May the Force Be With You
A push or pull that causes an object to move, stop, or change directions.
What is a force?
bicycle wheels
moving a distance in a certain amount of time
What is speed?
Work is found by multiplying force and this
What is distance?
An object at rest will remain at rest until this happens.
What is "an outside force acts on it"?
Force of pushing or pulling between magnetic poles
What is magnetism?
see saw
What is a lever?
a speed in a particular direction
What is velocity?
If a person pushed a desk with 400 Newtons of force but it didn't move, this amount of work was done.
What is zero newtons?
When a greater force is applied to an object with a certain mass, this increases.
What is acceleration?
Force that opposes or stops motion when two surfaces rub against each other
What is friction?
What is an inclined plane?
any change in an object's motion, or velocity
What is acceleration?
The amount of work done when a book (force of 3 Newtons) is lifted 2 meters off a desk.
What is 6 joules?
Newton's second law of motion is shortened to this equation.
What is "Force=Mass x Acceleration" or F=ma?
Force that pulls all objects toward each other
What is gravitation?
axe head
What is a wedge?
A measure of how hard it is to slow down or stop an object
What is momentum?
The device that is used to make work seem easier by changing the distance, or the size or direction of a force
What is a simple machine?
For every action force there is an equal and opposite one of these.
What is a reaction force?
Value of combined forces on an object
What is net force?
a flagpole
What is a pulley?
The planets stay in orbit due to gravity and this property of matter that resists change to movement.
What is inertia?
The use of force to move an object through a distance
What is work?
When a person pushes against the wall with 20 Newton, the wall exerts a force back on the person with this amount of force.
What is 20 Newtons?
