Chapter 6
Compound that releases HYDROGEN ions in water
a push or pull exerted by one object on another.
a force that resists motion by way of contact between two things
What do machines do?
Machines reduce the force to do a constant amount of work.
Define Vector.
what is sliding friction?
a force that resists motion as two things slide across each other.
What is energy?
What is mechanical energy?
kinetic or potential energy associated with the motion or position of an object.
a solution that contains a large amount of solute relative to the amount that could dissolve.
the speed of something in a given direction.
What is rolling friction?
resistance of motion caused by a round object rolling across another object.
What's a complex machine?
What is kinetic energy?
the energy an object has due to its motion.
Define neutralization.
a chemical reaction in which an acid and a base react quantitatively with each other.
what is fluid friction?
a force that resists motion of an object due to a liquid or gas.
What's a subsystem?
What is elastic potential energy?
the potential energy associated with objects that can be stretched or compressed.
what is inertia?
The tendency of an object to resist movement or a change in movement.
What does a pendulum do work on?
It puts force, therefore work, on the air to push it out of the way.
What is gravitational potential energy?
potential energy that depends upon an object's height.
