100

The units of acceleration

m/s2

100

Gravity affects which component of a projectile's motion?

Vertical

100

An object experiencing a buoyant force of 10 N weighs 9 N. Will it float?

yes

100

The formula for mass number

protons + neutrons

100

What it's called when a falling object is experiencing a force of air resistance equal to the force of gravity acting on it

terminal velocity

200

The difference between speed and velocity

Velocity involves the direction

200

Newton's 1st Law

Object at rest will stay at rest, object in motion will stay in constant motion, unless acted upon by an unbalanced force

200

You press on the top of a balloon. Where in the balloon does pressure increase?

everywhere

200

The outermost electrons in an atom

valence electrons

200
Carbon-12 and Carbon-14 are different what?

Isotopes

300

This is defined as an object's resistance to motion

Inertia

300

Newton's 2nd Law

F = ma

300

Archimedes' Principle says that buoyant force acting on an object is equal to what?

The weight of the fluid that the object displaces

300

The type of chemical bonding that two nonmetals bonded together experience

covalent bonding

300

The value of the acceleration due to gravity on Earth

9.8 m/s2

400

You walk 4 meters forward and 4 meters backward.

1. what is your displacement?

2. what is your distance traveled?

1. 0 meters

2. 8 meters

400

The two factors that determine the force of gravity between two objects are ______ and ______

mass, distance

400

What causes buoyant force?

A difference in pressure above and below and object

400

The ion that Aluminum will form

Al3+

400

The chemical formula for lithium sulfide

Li2S

500

Is there a net force acting on an object that is moving in a circle at constant speed?

1. yes, no or it depends

2. explain

1. yes

2. velocity is changing because direction is changing. acceleration involves changing velocity. since the object is accelerating, there is a net (unbalanced) force

500

If the force of gravity on a falling ball on Earth is the action force, according to Newton's 3rd Law, what is the reaction force?

force of ball pulling up on Earth

500

Bernoulli's Principle

faster moving fluids create lower pressure, slower moving fluids create higher pressure

500

I bond in a 1:2 ratio with magnesium and I'm located in the same period as the element with atomic number 15. What element am I?

Chlorine
