100
This is a measure of the change in the velocity or direction of a moving object.
What is acceleration?
100
If forces are canceled out, they are _________ forces.
Balanced
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
Newton's ______________ law states that an object with a greater mass will be harder to move than an object with less mass.
2nd
200
Newton’s Second Law can be summarized using this equation.
What is force = mass x acceleration?
200
This property of matter increases with its mass.
What is inertia?
200
A semi truck takes longer to slow down than a car is an example of Newton's ____________ Law of Motion.
Second
200
Pulling a table cloth from a table and not disturbing the dishes on top is an example of Newton's ___________ Law of Motion.
First
200
This is the tendency of an object to resist a change in its motion.
What is inertia?
200
An object at ___________ will stay at ___________ and an object in _____________ will stay in ______________ unless an unbalanced force acts upon it. This is known as Newton's _______ Law of Motion.
rest, motion, 1st
300
One object pushing on another will always receive a push in return. True or false.
True
300
Objects with more mass are ______ to set into motion.
harder
300
Paddling a canoe to make a boat move is an example of Newton's __________ Law of Motion.
Third
300
This natural law states that for every action, there is an equal and opposite reaction.
What is Newton’s Third Law?
300
The picture shows you how to calculate Newton's _____ Law of Motion.
Second
300
Newton's _________ law states that every action there is an ____________ and ___________ reaction.
3rd, equal, and opposite
400
What causes a ball that has been kicked across the ground to stop?
Friction
400
The attractive force that exists between all objects that have mass is known as _______________.
Gravity
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
Newton's Second Law uses the formula: F = ma What do the variables represent?
Force = mass x acceleration
500
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened to the acceleration?
The objects acceleration increased.
500
This is the acceleration of gravity and its appropriate units.
What is 9.8 meters per second squared?
500
A ball bounces away when another ball hits it. Which law does this demonstrate?
Newton's 3rd law.
500
Your car has a mass of 2500 kg and force of 5000 N. How fast will it accelerate? Don't forget the units are measured in meters per second square.
2 m/s square
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
What are the three NATURAL forces on Earth that slow objects down or make them change direction. One of these forces pulls people to the center of the Earth, the other occurs sometimes with wind, and the other is a result of pressing two objects together.
Gravity, Air Resistance, Friction
