Physics 1 Flashcards
List some forces
Gravity.
Tension.
Normal (Contact) Force.
Kinetic Friction.
Static Friction.
Air Resistance (Drag)
Elastic (Spring) Force.
What are resultant forces
the total amount of force acting on the object or body along with the direction of the body
What’s friction
Things rubbing up against each other, The resistance that one surface or object encounters when moving over or through another material
WHat is mass
Mass is the amount of matter in an object. Mass is measured in kilograms (kg).
What is weight
Weight is a force due to the pull of gravity on an object. Weight is a force and so is measured in newtons
What are the energy stores
magnetic.
internal (thermal)
chemical.
kinetic.
electrostatic.
elastic potential.
gravitational potential.
nuclear.
How do you calculate energy
Energy = Power x Time
