What is the equation to find velocity?
What is distance/time.
200
What is the equation for acceleration?
What is velocity/time or speed/time.
200

What is LARGE!
200
What is density?
What is the amount of particles in a given area of an object.
300
What is the speed of a bicyclist that can travel 60 miles in 2 hours?
What is 30 mi/hour
300
What is the acceleration of a jet if it goes from 0 to 60 m/s in 12 seconds?
What is 5 m/s2.
300
When throwing a paper airplane, what three forces acts upon the plane?
What are friction, push, and gravity.
300
Why should you wear a seat belt?
What is so you will not fly out of the car upon collision (you will be part of the car if you put on a seat belt, so you will stop with the car).
300
What does buoyancy make possible?
What is floating.
400
What distance does a swallow flying 20 m/s go in 90 seconds?
What is 1800 meters.
400
What is the acceleration of a car that goes from 10 to 20 mph in 0.2 hours?
What is 50 mph2.
400
What is the net force and its direction? 15 N left 8 N right
What is 7 N left.
400
Why was it so hard for the Titanic to turn?
What is it has a large mass so it does not change motion easily/it wanted to stay in motion.
400
An object has a volume of 50 mL. It has a mass of 25g. What is its density?
What is 0.5 g/mL
500
What is difference between speed and velocity?
What is velocity has a direction and a magnitude, speed only has a magnitude. Velocity is a vector and speed is not.
500
What is the speed of an elephant that accelerates at 3.5 m/s2 in 20 seconds?
What is 7 m/s
500
What is the net force? 10 N left 25 N right 60 N up 40 N down
What is 15 N right, and 20 N up.
500

What is #2, and #3.
500
TRUE or FALSE: If the buoyant force pushing upwards on a object is greater than gravity pulling down, then the object will sink.
What is FALSE. It will float!
