Newtons Laws 1
This is a measure of the change in the velocity or direction of a moving object.
acceleration?
This is the acceleration of gravity and its appropriate units.
9.8 meters per second squared
The Unit of force is this.
What is the Newton?
This states that an object’s motion will not change unless an unbalanced force acts on the object.
Newton's First Law?
What does the m stand for in F= ma?
Mass
What is an infant whale called?
Newton’s Second Law can be summarized using this equation.
force = mass x acceleration?
If forces are canceled out, they are _________ forces.
Balanced
Weight is measured in ______.
Newtons
Which law? F=mxa
Newton's 2nd law
This is the tendency of an object to resist a change in its motion.
inertia?
What does the "N" stand for in NATO?
North
One object pushing on another will always receive a push in return. True or false.
True
This property of matter increases with its mass.
inertia?
What external force helps keep a frisbee floating in the air?
Air Resistance
This natural law states that for every action, there is an equal and opposite reaction.
Newton’s Third Law?
True or False: Earth is the only planet that has gravity.
False
The study of the weather is called what?
Meterology
What causes a ball that has been kicked across the ground to stop?
Friction
Objects with more mass are ______ to set in motion.
harder
A car and a train are going the same speed. The car is easier to stop because of this.
less mass and less inertia
When you stop quickly on your bike what term is used to explain why you fly forwards?
Inertia
This is required to overcome an object’s inertia.
unbalanced force?
Which elements from the periodic table is found in a thermometer?
Mercury
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?
The objects acceleration increased.
This is the measure of the force of gravity pulling down on an object of given mass.
weight
A ball bounces away when another ball hits it. Which law does this demonstrate?
Newton's 3rd law.
What is Newton's first name?
Isaac
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
How many planets in our solar system have moons?
