I don't have the ENERGY!
The ability to do work.
What is energy?
Definition of sound energy.
What is a form of mechanical energy that is carried by sound waves?
The definition of electrical energy.
What is the energy associated with moving charged particles?
The process of energy changing from one form to another.
What is energy conversion?
Definition of work.
What is the product of a force (applied in the direction of motion of an object) and the distance the object moves?
How the kinetic energy of an object is determined.
What is multiplying half of an object's mass by the square of its speed?
KE= 1/2 x M x V2
Sound energy
What is produced when an object vibrates?
The electrical potential energy in clouds is transferred into these 3 types of energy in a lightning bolt.
What is light energy, sound energy and thermal energy?
A system where nothing can enter or leave.
What is a closed system?
The unit of work.
What is a joule?
The factors that determine the gravitational potential energy of an object.
What is object mass, acceleration due to gravity and the height relative level (often the ground)?
PE = M x G x H
How nuclear fission releases energy.
What is 'by splitting atomic nuclei apart'?
The definition of electromagnetic energy.
What is a form of energy that is reflected or emitted from objects and travels through space in the form of waves?
Law of conservation of energy.
What is energy cannot be created or destroyed; it can only be converted from one form to another or transferred from one object to another?
True or false, if a force does not act in the direction of the object’s motion, it does no work on the object.
What is true?
The type of energy that a compressed pogo stick has.
What is elastic potential energy?
The combining or fusing the nuclei together of smaller atoms to form a larger atom.
What is nuclear fusion?
The other names for electromagnetic energy.
What is radiant energy or light energy?
The type of potential energy a seagull uses when dropping an oyster onto rocks from high above.
What is gravitational energy?
Work output is always less than work input because of this.
What is friction?
The sum of an object's potential energy and kinetic energy.
What is mechanical energy?
Why no one can hear you scream in space.
What is 'there is no medium for sound waves to travel through'?
Why electromagnetic energy can travel through empty space.
What is radiant energy does not need to touch other matter to transfer the energy?
Forces that caused the pendulum to slow down and eventually stop when you did experiment 1.2.
What is frictional force?
1) It changes the size of a force.
2) It changes the direction of a force.
3) It changes the distance over which a force is applied.
What are the 3 ways that a machine changes force?
