What is velocity?

• the quickness of an object
• the location of an object
• the acceleration of an object
• the speed in a specific direction

When one object is travelling with a constant velocity, its acceleration will be 

• decreasing
• increasing
• constant
• zero

Velocity is:

• speed with direction

• the same as speed

• just a direction

• acceleration and a specific direction

meters per second (m/s) is a unit of:

• speed
• distance
• acceleration
• gravity

What is another name for balanced forces on an object that result in a net force of zero?

• gravity
• air resistance
• equilibrium
• friction

If you drop a feather and a coin at the same time in a vacuum tube, which will reach the bottom of the tube first?

• the coin
• the feather
• neither, they will both hit at the same time
• it depends on the length of the tube
