Kinetic Energy
This is the energy of an object in motion.
What is kinetic energy?
This is the energy of heat.
What is thermal energy?
What is potential energy?
What is the stored energy an object has due to its position, state, or configuration, ready to do work.
A book resting on a table is an example of this type of force, where gravity pulling down is met by the table pushing up.
What are balanced forces?
This law explains why you need to wear a seatbelt in a car.
What is Newtons first law (Inertia)?
True or False: Bowling uses kinetic energy.
What is True?
This type of energy is stored in the bonds of atoms and molecules.
What is chemical energy?
Name one of the two main types of potential energy discussed in physics.
What is gravitational or Elastic (or Chemical, Electrical).
The tendency of an object to resist changes in its motion.
What is inertia?
For every action, there is an equal and oppsosite...
What is a reaction?
What two things does kinetic energy depend on?
What is mass and velocity?
Energy caused by vibrating particles in a medium.
What is sound energy?
When a ball is thrown up, what happens to its potential energy as it rises?
It increases (as height increases).
When these forces act on an object, its motion changes (speeds up, slows down, or changes direction).
What are unbalanced forces?
What is force?
As an object moves faster, its kinetic energy...
What is increases
The main force that gives gravitational potential energy its "potential".
What is gravity?
This is the single force that results from combining all forces acting on an object (e.g., the difference in a tug-of-war).
What is the net force?
Newtons third law is also known as this law.
What is the law of action and reaction?
The two factors that affect how much kinetic energy an object has are mass and this other quantity.
What is speed (or velocity)?
This form of energy is stored in foods and fuels.
What is chemical energy?
True or False: A person standing still has zero kinetic energy but some potential energy.
What is True?
A soccer ball rolling across the grass experiences this force, causing it to slow down and stop.
What is friction (or unbalanced force)?
According to newtons second law, acceleration is directly proportional to force and inversely proportional to this.
What is mass?
