Newtons 1st law
What is the first law of motion?
The first law of motion is when an object at rest stays at rest and an object in motion stays at motion, until and unbalanced force occurs.
What is the second law of motion?
The amount of force applied to accelerate an object's mass.
While driving down the road, a firefly strikes the windshield of a bus and makes a quite obvious mess in front of the face of the driver. Which force is greater: the force on the firefly or the force on the bus?
Each force is the same size. For every action, there is an EQUAL and opposite reaction.
What is the equation for calculating forces?
F=M x A
What is Newton's full name?
(Sir) Isaac Newton
If you're riding a skateboard and hit a curb what is most likely to happen
It's most likely to happen that your body goes off flying because the hit only stops the board not you.
As the force acting upon an object is increased, what else is also increased?
The acceleration of an object also increases.
True or False: For every action, there is an equal and opposite reaction.
True
What is Inertia?
This is the natural tendency of objects to keep on doing what they're doing.
What measures the quantity of matter of an object?
Mass
What happens when an object in motion crashes into an object at rest?
The moving object will stop for split seconds but will try to continue moving in the same direction or it will go to the opposite direction.
How could you tell if a moving object is receiving an unbalanced force?
It might speed up, slow down, or change direction
True or False: Forces always come in pairs - known as "action-reaction force pairs "
True
What is an example of inertia? A. falling over a bridge B. tripping over a banana peel C. breathing D. moving forward in your seat when the car stops abruptly
D. moving forward in your seat when the car stops abruptly
What is the gravitational force?
The gravitational force is a force that attracts any object with mass.
How long will an object remain at rest?
It will remain at rest as long as it takes for the object to encounter an unbalanced force.
The amount of force that gravity has on an object is affected by what factors ?
The object's mass and the object's distance from the gravitational force.
Give one particular everyday situation in which we see Newton's Third Law of Motion occurring.
(answers vary-must demonstrate forces acting in pairs and equal and opposite to one another)
What do you call forces that are opposite and equal?
Balanced
This is the standard unit used for describing the value of Force.
Newtons (N)
What is force?
a push or a pull.
For every ______ there is an equal and opposite ________.
Action, Reaction
What does Newton's 3rd Law of Motion mean?
It means that in every interaction, there is a pair of forces acting on the two interacting objects.
An object will _________________ in the direction that you push it.
Accerlerate
Forces that cause a change in the motion of an object are considered this.
What is unbalanced (forces)?
