Vocabulary
The force that pulls all object towards each other.
What is gravity?
Another name for the law is Inertia.
What is Newton's first law?
Apparatus made of metal alloy that is used to hold a test tube for heating.
What is a test tube holder?
A cup and crayon equals 3 ounces, if the cup equals 2 ounces, how many ounces is the crayon?
1 ounce
The force that one surface exerts on another surface when the surfaces come into contact with one another.
What is friction?
A place or object used for comparison to determine if an object is in motion.
What is a reference point?
An object at rest stays at rest, an object in motion stays in motion with the same velocity and in the same direction, unless acted upon by unbalanced force.
What is newton's first law (inertia)?
Apparatus that consists of a long metal rod and stand Used for holding clamps and iron rings during experiments.
What is a laboratory stand?
Estimate how many grams a toy car weighs in grams.
30-45 grams?
Comes into play when a body is forced to move along a surface but movement does not start. (no motion)
What is static friction?
The overall rate of speed at which an object travels or moves; calculated by dividing the total distance an object travels by the total time.
What is average speed?
Explains behavior of an object. Acceleration of an object is dependent upon two variables- the net force acting upon the object and the mass of the object. As the force acting upon an object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
What is newton's second law?
Apparatus that acts as a gas burner. Used with a striker and safety glasses.
What is a Bunsen burner?
What weighs more, a pound of bricks or a pound of feathers?
Both, a pound is a pound no matter the object.
A force that slows down the motion of a rolling object. Basically, it is a combination of various types of frictional forces at point of contact of wheel and ground or surface. When soft object moves over a hard surface then its distortion makes it slow down.
What is rolling friction?
The product of an objects mass and velocity.
What is momentum?
For every action, there is an equal and opposite reaction.
What is newton's third law?
Liquids are allowed to evaporate using heat or room temperature leaving behind solid residue. Can be used with Bunsen burner, clamps, laboratory stand,etc.
What is an evaporating dish?
If 1 pound is equal to 16 ounces, how many ounces is a ten pound bag of potatoes.
160 ounces.
Occurs when two objects slide over each other.
What is sliding friction?
Determines if an object moves and in which direction.
What is net force?
A baseball player is up to bat, before he hits the baseball off of the t-stand, what law represents the baseball.
What is newton's first law?
Fine wire mesh with ceramic center. Used when heating beaker or flask over a Bunsen burner.
What is a wire gauze?
There's 28 grams to a pound, so how many grams are in a 8 pound box a papers?
224 grams.
When a body moves in a fluid or in air then there exists a resistive force which slows down the motion of the body. A freely falling acts in the upward direction or in a direction opposite to skydiver's motion.
What is fluid friction?
