Solvent and solute
If I were to make hot chocolate what would be the solvent and what would be the solute.
Hot chocolate mix solute
water solvent
What do all objects have
mechanical energy
What is force measured in
Newtons
What is gravitational force impacted most by
Mass and the distance of two objects
What is friction
Friction slows things down and prevents machines from having 100% efficiency
If water is cold at what rate does the solute dissolve in a solvent
Slower
What is a simple machine
to make work easier
How is sound energy transferred
In vibrational waves
Battery store which type of energy
Chemical
If two students are pushing a table. One with 4N and another with 6 N then they are using how much force
10N
How would you make a solvent dissolve faster
Shake or mix
Simple machines reduce the amount of work needed true or false
False
True or false all simple machines exert a force in the same direction the object moves. If true explain, if false explain
false
When the battery is being used what energy does it change into or is converted into
From chemical to electrical
How is motion calculated
I either adding or subtracting the force is being applied
At what rate would the solute dissolve in a solvent if the solvent was hot
Faster
Name another type of inclined plane
wedge
Name all five simple machines
incline planes, wheel & axle, screw, pulley, and lever
Name all the types of energy
Nuclear chemical electrical electromagnetic and thermal
What is the law of conservation of energy
When chemical energy changes electrical energy no energy is being lost or created
What is kinetic energy
The energy an object has when it is in motion
What is potential energy
The energy an object has when it is at rest
When using a simple machine what is transferred
Mechanical energy
What is the equation for force
Force equals mass times acceleration
Name all three of newtons laws of motion
1. An object in motion will stay in motion. An object at rest will stay at rest
2. Eight acceleration depends on the objects mass and velocity. Objects with a larger mass will need more speed to accelerate objects with a smaller mass will need less speed to accelerate
3. If equal forces are applied in an opposite direction there will be no motion
