Newtons Laws Of Motion
An object at rest will remain at rest, unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force. (This law is often called “the law of inertia.” Which Law is this?
First Law
What pulls objects down to the ground and makes it difficult to fly things in the air.
Gravity
What does it mean when an object has reflectional symmetry?
Object will look exactly the same if it is reflected across a line of symmetry. Mirror Image
when was the first rocket invented and where?
1100 AD in china
Launching a rocket relies on which law?
Third Law
What force pulls someone or something along forcefully, roughly or with difficulty?
Drag
What's it mean if something is symmetrical?
The same on both sides
What shape do rockets need to have that will allow them to cut through the air easily?
Aerodynamic shape
For every action, there is an equal and opposite reaction. What law is this?
Third Law
What is explained as a strong push that can cause your object to move upward against gravity?
Thrust
What's it mean if something is asymmetrical?
having two sides that are not the same
Rocket engines burn a combination of chemicals called what?
Propellant
A stationary object with no outside force will not move. What law does this refer to?
First Law
What force deflects air downward, and the reaction pushes the wing up?
Lift
Snowflakes are not white nor blue, they are?
Translucent
Friction between the object in the air and the air itself that causes things to slow down is referred to as what?
Air resistance
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated), the greater the amount of force needed (to accelerate the object).Which law is this?
Second Law
if something can easily travel through the air with very low air resistance that would be referred as?
Aerodynamics
How many points do snowflakes typically have?
6
What speed do rockets have to reach to be stronger than gravity? This is known as escape velocity.
7 miles per second or 25,000 miles per hour.
