Newtons Laws
Astronomy
100
This is a measure of the change in the velocity or direction of a moving object.
What is acceleration?
100

This is the acceleration of gravity and its appropriate units.

What is 9.8 meters per second squared?

100

The Unit of force is this.

What is the Newton?

100
This states that an object’s motion will not change unless an unbalanced force acts on the object.
What is Newton's First Law?
100
The SI unit of acceleration is this.
What is meters per second squared?
100

Why is the center of a black hole "invisible"?

Light can't escape

200
Newton’s Second Law can be summarized using this equation.
What is force = mass x acceleration?
200

If forces are canceled out, they are _________ forces.

Balanced

200

The Unit of Weight is this.

What is Newton?

200

Which law? F=mxa

Newton's 2nd law

200
This is the tendency of an object to resist a change in its motion.
What is inertia?
200

What creates a black hole?

When massive stars run out of fuel they collapse in on themselves and can form a black hole.

300

One object pushing on another will always receive a push in return. True or false.

True

300
This property of matter increases with its mass.
What is inertia?
300
This property of a moving object makes it hard to stop.
What is momentum?
300
This natural law states that for every action, there is an equal and opposite reaction.
What is Newton’s Third Law?
300

All objects in the universe are attracted to all other objects in the universe. True or False?

True

300

Why is Pluto not considered a planet?

The orbit of Pluto is undetermined.

400

What causes a ball that has been kicked across the ground to stop?

Friction

400

Objects with more mass are ______ to set in motion.

harder


400
A car and a train are going the same speed. The car is easier to stop because of this.
What is less mass and less inertia?
400

This occurs whenever an object is acted upon by an unbalanced force.

What is acceleration or motion?

400
This is required to overcome an object’s inertia.
What is an unbalanced force?
400

What is the term called if YOU get pulled into a black hole?

Spaghettification

500

According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?

The objects acceleration increased.

500
This is the measure of the force of gravity pulling down on an object of given mass.
What is weight?
500

A ball bounces away when another ball hits it. Which law does this demonstrate?

Newton's 3rd law.

500
The SI unit of mass is this.
What is kilogram?
500

If the outward push of air is greater than the inward push of the rubber on a balloon the balloon would deflate.

False- Balloon would inflate/pop

500

How will our sun's "life" end? (What is the fate of our sun?)

Our star will grow to be larger than we can imagine — so large that it'll envelope the inner planets, including Earth. That's when the sun will become a red giant. Eventually run out of fuel turning into a white dwarf and burning out. NO BLACK HOLES!!!!
