Which of the following is the correct definition of velocity?

An object's change in position relative to a reference point

Which of the following is an example of a force at work?

An elephant pushing over a tree

The sun giving off heat and light through radiation

How many poles does a true magnet have?

4 poles- North, South, East, West

What is an electromagnet?

A temporary magnet created from an electric current running through a ferromagnetic medium

An instrument containing a magnetized pointer that shows the direction of magnetic north and bearings from it.

An item with 3 magnetic poles due to the electric current running through it

The invisible field of electricity surrounding a magnet

If you rub your socks on a carpet, there is a high chance you can shock someone else with static electricity. Why do you not get shocked though?

The flow of electrons goes from negative to positive and you have a high negative charge built up on your body

You are creating an open circuit and electricity can flow through an open circuit

You have a higher resistance to electricity because of the type of shoes you are wearing

You have superpowers (but not really)

A football player tries to move a sled across a practice field, however the sled does not move. Why does the sled not move?

The static friction is too great because not enough force can be applied to move the sled

There is too much rolling friction

Not enough normal force is being applied, causing the sled to move backwards

There is not enough fluid friction to move the sled

How are wheels and parachutes similar?

They interact with various substances to either increase, or reduce friction

Wheels are for cars and parachutes for capsules/skydivers

Only parachutes reduce friction. Wheels increase it

Which of Newton's Laws of Motion involves the equation Force= Mass x Acceleration? It is also where the acceleration depends on the mass of the object and the amount of force applied

Newton's third law of action/reaction

Atoms are usually more stable and unlikely to form other bonds when they...

have full valence electrons (8)

How many more electrons are needed to fill an outermost energy level of a Carbon atom?

Carbon is a nonmetal, it has no electrons

Covalent bonding is where:

Elements share electrons to bond

Electrons are given or taken from another element to bond

What is a valence electron?

An electron found in the outermost shell of an atom

An electron found in the middle shell

An electron found inside the nucleus of an atom
