Physical Science 1
A push or a pull exerted on an object is called what?
Force
True or False? The Watt unit was named after a scientist
true
What is another name for Newton's 1st Law of Motion?
Law of Inertia
DOUBLE POINTS!!! List the 7 colors of the Rainbow in order.
Red, Orange, Yellow, Green, Blue, Indigo, Violet
Which term means you can see through a material, completely?
Translucent, Transparency, or Opaque?
Transparency
NAME two greenhouse gases
Carbon Dioxide NH4
How many Newton's Laws are there?
3
This is the force resisting motion. It slows things down.
Friction
When a spring is held together, what energy is this called?
ELASTIC potential energy
DOUBLE POINTS!!! In this type of material, you can "kind of" see through it.
Translucent
The process of gathering information through the senses.
Observation
This is the rate of change of velocity. Calculated by dividing the change in the velocity by the time it takes the change to occur. Is it: motion, acceleration, or speed?
Acceleration
DOUBLE RAAC POINTS!!! A pulling force that works across space. It begins with the letter G.
Gravity
In order to see the rainbow colors, we had to look through the Spectroscope facing any source of what?
Light
In this type of material, you cannot see through it at all.
Opaque
The greater the mass of the object, the greater or lesser the force needed to achieve the same change in motion.
greater
Imagine you are holding a cup on top of your head while standing on a desk.
What object has the most potential energy?
You!
While the cup is at a higher gravitational energy, you have more mass than the cup.
Tendency of an object to resist any change in its motion.
Inertia
Force = Mass x Acceleration
Which Newton's Law of Motion is associated with this formula?
Newton's 2nd Law of Motion
In a solution, the substance being dissolved is called what?
a solute
Name 3 parts of the electromagnetic spectrum and where they lie on it.
1. Radio waves
2. Microwaves
3. Infrared Rays
4. Visible Light
5. Ultraviolet Rays
6. X-Rays
7. Gamma Rays
What is the process of an object moving or being moved called?
motion
This is a measurement of mass in motion. Any moving object has this.
Momentum
For every action, there is an equal and opposite reaction. Which Newton's Law of Motion talks about this?
Newton's 3rd Law of Motion
Name the 3 states of Matter.
List an example of each with one material.
How does it change from those states of matter?
Solids, liquids, and gas
Ice, water, and water vapor
Ice condensates into water.
Water evaporates into water vapor.
