Motion & Forces
What Is a gravity?
This force pulls objects toward the center of the Earth
The three most common states of matter are solid, liquid, and this.
Gas
What is kinetic energy?
This is the energy of motion.
Electron is...
This subatomic particle has a negative charge.
What is an unbalanced force?
Newton’s first law, also called the "law of inertia," states that an object at rest stays at rest unless acted on by this.
Newton’s first law is also known as this "lazy" law.
What is the law of inertia?
The smallest unit of an element that retains its properties
Atom
What is temperature?
The measure of the average kinetic energy of molecules in a substance.
What is static electricity?
The buildup of electric charge on an object.
What is force?
The equation F = ma represents Newton’s second law, where F stands for this quantity
Who is Isaac Newton?
The acceleration of an object depends on force and mass, according to this scientist’s second law of motion.
When a solid turns directly into a gas, skipping the liquid phase, this process occurs.
sublimation
What is conduction?
The process where heat transfers through direct contact.
What is a circuit?
A closed loop in which electric current can flow.
The reason rockets are able to launch into space is explained by this law, which states that every action has an equal and opposite reaction.
What is Newton’s third law?
What is inertia?
The tendency of an object to resist changes in motion is called this.
The amount of space an object occupies.
Volume
What is the law of conservation of energy?
This law states that energy cannot be created or destroyed, only transformed.
The unit used to measure electrical resistance.
Ohm
What is a Newton?
The unit of force in the metric system.
This force opposes motion and produces heat when two surfaces rub together.
What is friction?
What is viscosity?
liquid’s resistance to flowing, like how honey is thicker than water.
What is convection?
The transfer of heat in fluids by the movement of currents.
Who is Michael Faraday?
This scientist discovered the relationship between electricity and magnetism.
What is momentum?
