What is matter?
Matter is anything that takes up space.
Mass is the measure of matter.
Who created the laws of motion?
Issac Newton
What is gravity?
A force that pulls an object toward the center of a body of mass (earth)
How are weight and mass different?
Mass never changes. Weight can change depending on location.
What is the 1st law of motion?
An object in motion stays in motion unless stopped by an opposing force.
What is mass?
Mass is the measure of matter in an object.
How are electric and magnetic forces related?
Electric force acts between all charged particles, magnetic force only acts between moving ones.
What is the 2nd law of motion?
The greater the mass of an object the more force it takes to move it.
What is weight?
A measure of the force of gravity in an object.
How are synthetic and naturual resources similar?
Both are made from natural resources (but synthetic are changed)
What is the 3rd law of motion?
For every action, there is an equal and opposite reaction.
What is synthetic material?
A synthetic material is originally made from natural resources, but was chemically altered.
How are electric and magnetic forces related?
they both attract and repel electric charge
What is the law of conservation of mass?
The mass of a closed system must remain constant over time.
