100
Define potential energy.
What is the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system?
100
Define Newton's three laws of motion.
What is: First law: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction. Second law: When a force acts on an object, it will cause the object to accelerate. Third law: For every action, there is an equal and opposite reaction.
100
What is the difference between generators and motors?
What is the generator produces energy and the motor uses energy?
100
What are the charicteristics of acids?
What is sour, stings on skin, reacts with metals, electrolyte?
100
Define alternating current.
What is an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies?
200
Define kinetic energy.
What is the energy of a body or a system with respect to the motion of the body or of the particles in the system?
200
Give an example for Newton's three laws of motion.
What is: First law: A car running inot a brick wall and the driver flying through the windsheild. Second law: Kicking a soccer ball. Third law: Pulling on a rope to lift a heavy object.
200
What is an electromagnet, and how do you increase the strength of the electromagnet?
What is a soft metal core made into a magnet by the passage of electric current through a coil surrounding it; you can increase the strength by increasing the amount of coils, increasing the current flow, or by passing an iron core through the electromagnet.
200
What are the characteristics of bases?
What is bitter, slippery, smooth, no reaction, electrolyte?
200
Define solute.
What is the minor component in a solution, dissolved in the solvent?
300
What is the Law of Conservation of Energy?
What is the principle that in a system that does not undergo any force from outside the system, the amount of energy is constant, irrespective of its changes in form?
300
Define mass, weight, and inertia?
What is: Mass: The amount of matter in an object. Weight: The measure of heavieness on an object. Inertia: The tendency of a body to resist acceleration.
300
What is a permanent magnet?
What is a magnet that retains its magnetic properties in the absence of an inducing field or current?
300
Name three ways you can increase the rate the rate of dissolving.
What is heating it up, stirring it, or using a catalyst?
300
What are three ways static charges can occur?
What is 1: Moving your feet around on the carpet 2: Rubbing a balloon on your head 3: Your hair sticking up on a trampoline
400
Define conduction, convection, and radiation.
What is Conduction: The transfer of heat between substances that are in direct contact with each other. Radiation: When elcetromagnetic waves travel through space. Convection: The up and down movement of gasses adm liquids caused by heat transfer.
400
At what rate does the Earth's gravity pull on all objects?
What is 9.8 meters a second
400
Define the two types of circuits.
What is Series circuit: a circuit having its parts connected serially. Parallel circuit: a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
400
What are the pH of acids and bases?
What is: acids- 0-6 bases- 7-14
400
How do you calculate an object's weight?
What is Mass x Acceleration
500
Give an example of all three forms of heat transfer.
What is Conduction: Heat moving from a burner to a pot while cooking. Radiation: The sun raising the temperature of a house. Convection: Hot air making a hot air balloon rise.
500
What is the standard unit of mass in the metric system?
What is A kilogram (kg)
500
What is a direct current?
What is an electric current flowing in one direction only?
500
What happens to the particle motion if there is an increase in temperature?
What is the particle moves faster?
500
