Type of force
This force is responsible for slowing down a moving object on a surface?
What is friction
This is the formula for velocity
What is dissplacement / time?
v=d/t
What factors affect gravity?
Gravitational force increases if the mass of the objects increases and decreases if the distance between them increases.
AU
This force is exerted by a rope, cable, or string when pulled tight?
What is Tension Force?
This is an ion
What is an atom or molecule that has a charge due to having lost or gained electrons
Is gravity a force or a curve?
Newton described gravity as a force, while Einstein described it as the bending of space and time.
How are elements arranged?
By increasing atomic number
This force makes a refrigerator magnet stick to a metal surface?
What is the Magnetic Force?
This is the formula for density
What is mass / voulme
d=m/v
What are cations?
positively charged ions that have lost e-
What is escape velocity?
The speed needed to break free from a planet's gravity, which depends on the planet's mass and radius, not the object's mass.
What are vertical columns called?
Groups or Families; they share similar chemical properties due to having the same number of valence electrons.
This is the force in a stretched rubber band or compressed spring?
What is Elastic Force (or Spring Force)?
This is the formlua for speed
What is distance / time
s=d/t
What are anions?
negatively charged ions that have gained e-
Does gravity affect light?
Yes, gravity can bend light, a principle of general relativity.
What are horizontal rows called?
Periods; they indicate the number of electron shells.
What are the four fundamental forces of nature?
What are: Gravitational, Electromagnetic, Strong Nuclear, and Weak Nuclear forces
How do electrons jump between energy levels without passing through?
how they jump between energy levels without passing through the space in between, why they don't fall into the nucleus, and what "shape" they actually have
What happens at the center of the Earth?
Gravity would not be felt at the exact center because the surrounding mass would cancel itself out.
Why does Nickel appear after Cobalt, despite having a lower average atomic mass?
Answer: Due to atomic structure, specifically the atomic number.
