Newton's First
Define Newton's First Law.
An object in motion tends to stay in motion unless acted upon by a net force.
Define Newton's Second Law.
F= ma, or net force, is equal to mass multiplied by acceleration
Define Newton's Third Law.
For every action there is an equal and opposite reaction.
The unit of time in the International System of Units, historically defined as 1⁄86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each
What is seconds?
Inertia is related to which of the following laws of motion?
Newton's First Law
The name for the first law of motion; a tendency to do nothing or to remain unchanged.
What is Inertia?
Why do heavier objects requires more force than lighter objects to move or accelerate?
It would require more force to change its speed or direction.
what happens when action and reaction don't cancel each other out?
Force is acted upon different objects.
What is the mass measured in Newton's second law of motion?
What is a gram?
Which of the following Newton's laws of motion can be used to calculate the force on a body?
Newton's Second Law; If a body has a net force acting on it, it is accelerated in accordance with the equation.
A contact force that opposes motion.
What is friction?
The size of the force applied and mass of an object.
What are the factors needed to determine acceleration?
What law is indicated when an untied balloon is let go?
Newton's Third Law; The balloon will quickly release its air, forcing it to travel through the air with equal force in the opposite direction.
The SI base unit of length (equivalent to approximately 39.37 inches), first introduced as a unit of length in the metric system.
What is meters?
In still water, when a person walks on a boat, what will happen to the boat’s motion?
The boat will move backwards, indicating an action reaction force.
How does this Law affect Tug of War?
The rope will stay in the same place if the forces are balanced, and will move if unbalanced.
How does Newton's Second Law affect Tug of War?
We could measure how hard it would be to pull the rope based on their masses and the acceleration they pull at.
Define Collision.
An instance of one moving object or person striking violently against another.
The base unit of mass in the International System of Units. It is a widely used measure in science, engineering and commerce worldwide.
What is Kilograms?
If the mass of a bus is 2000 kg, what will the force required to speed up a bus at the 6m/s^2?
12000 N
What is the likely outcome if you're riding a skateboard and collide with an obstacle, such as a curb, using the front of your wheels?
You fly off the skateboard because your body will move, but not the board
The vector sum of all forces acting on an object.
What is Net Force?
How does Newton's Third Law affect Tug of War?
one team pulls the rope towards themselves with a certain amount of force and the opposing team is putting out force on the rope as well.
Unit of force in the International System of Units. It is defined as, the force which gives a mass of 1 kilogram an acceleration of 1 metre per second squared.
What is a Newton.
A force of 20 N acts upon a 5 kg block. Calculate the acceleration of the object.
4m/s^2
