What is a force
100
How fast something moves in a specific amount of time
What is speed?
100
When a force causes an object to move in the direction of the applied force.
What is work?
100
The two phases of matter that can be classified as a fluid.
What is gas and liquid?
100
The force that pulls us, and everything around us, toward the center of Earth.
What is gravity?
200
Unequal forces that do not have a net force of zero. These forces DO NOT cancel one another, which means there will be acceleration.
What are unbalanced forces?
200
The speed and direction of an object
What is velocity?
200
The formula for calculating work.
What is force X distance
200
The instrument used to measure atmospheric pressure.
What is a barometer?
200
A simple machine with an arm or rod that turns on a fixed point when a force is applied to it.
What is a lever?
300
Equal forces that act in opposite directions on objects and that have a net force of zero.
What is a balanced force.
300
The law of motion that states that an object at rest will stay at rest, an object in motion will stay in motion, unless an outside force acts upon it.
What is the Law of Inertia. Newton's First Law?
300
A type of machine that only has a few parts and no more than one movement
What is a simple machine?
300
Air pressure _________________ as you go higher in the atmosphere.
What is decreases?
300
The combination of a movable and fixed pulley.
What is a block and tackle?
400
The force that acts between surfaces touching one another.
What is friction?
400
The law of motion that states that for every action there is an equal and opposite reaction.
What is the of Conservation of Momentum. Newton's Third Law.
400
How much a force is increased by using a machine.
What is mechanical advantage?
400
Water pressure __________ as you go deeper in the ocean.
What is increases?
400
At sea level, the atmospheric pressure and the fluid pressure inside your body are _________________.
What is balanced or equal?
500
What are the five forces in our world?
What is electric force, magnetic force, buoyant force surface tension, muscle force
500
The law of motion that states that the greater the force of an object, the greater its acceleration. If the same force acts upon two objects, the object with less mass accelerates more than the object with more mass
What is The Law of Constant Acceleration. Newton's Second Law.
500
