Motion and Speed
As a car drives down the road, the distance between the car and a road sign changes, proving the car is this.
What is moving (or in motion)?
Miles per hour west is a unit of measurement for this.
What is velocity?
This force pulls all objects towards the center of the Earth.
What is gravity?
According to Newton's 1st Law, an object in motion will...this.
What is "stay in motion"?
We built this to minimize the force of the fall for our cargo.
What is a parachute?
This is the speed of a car that drives 10 miles in 30 minutes.
What is 20 mph?
Acceleration is a change in speed or this.
What is direction?
This is a push or a pull.
What is a force?
According to Newton's 2nd Law, this is equal to mass times acceleration.
What is force?
All rockets had to have a body, fins, and this part, which held the parachute.
What is a nose cone?
Speed is calculated by dividing distance by this.
What is time?
Acceleration is calculated by dividing speed by this.
What is time?
When all the forces acting on an object are balanced, this is the value of the net force.
What is zero?
The penny/index card trick works because of this law.
What is Newton's 1st Law?
The applied force acted on our rockets in this direction.
What is up?
This is a place or object used for comparison to determine if an object is moving.
What is a reference point?
This car can go from 0 mph to 60 mph in under 2 seconds, the fastest of all the cars we studied.
What is Tesla?
This force is is always in the opposite direction of motion.
What is friction?
This law is described by "Every action has an equal and opposite reaction".
What is Newton's 3rd Law?
This force pulled DOWN on our rockets, but UP on our parachutes.
What is air resistance?
In our Measuring Motion Lab, we measured the speed of different Hot Wheels cars. This is the name of the variable that is measured in a lab.
What is dependent variable?
A dog runs 102 meters in 3 seconds, then speeds up to 44 meters per second over 10 seconds. This is the dog's acceleration.
What is 1 m/s2?
Gravity pulls down all objects at this acceleration.
What is 9.8m/s2?
This is the tendency of an object at rest to stay at rest, or an object in motion to stay in motion.
This is the name of the launcher we used to launch our rockets.
What is an Aquapod?
