Newton's 1st Law
Fill in the blank- An object at rest remains at rest, and an object in motion remains in motion with the same velocity unless acted on by a force.
Unballanced
True or False
To increase acceleration add mass
False
How do you find forces
In pairs always
Fill in the blank- Force is a push or a .
Pull
Fill in the blank- The Law of Inertia is also referred to as .
Newton's First Law
Give an example of an unbalanced force
A rolling ball, a child jumping, etc. (Any unbalanced force)
Give the formula for force
Force= mass*aceleration
F=m*a
What do all 3 Law's combined help you do
The 3 Law's combined help you predict motion
Give an example of a force
Pushing a cart, throwing a ball, etc.
fill in the blank- Inertia is closely related to .
Mass
Define balanced force
A balanced force is an object at rest
What is the unit for force
Newtons or N
Explain action and reaction forces
Say you carried a box you apply force to the box and the box applies force on you. You applying the force is an action the box applying force on you is a reaction.
Define net force
The net force is the total force acting on an object at any given time.
Give an example of inertia
A car crash, etc.
Make a statement using the words balanced and unbalanced forces.
Any statement correctly using those words.
Give two examples of Newton's 2nd Law
Pushing an empty wheel barrel vs a full one, pushing an empty shopping cart vs a full one, etc.
True or False
If two objects act upon one another they will give off a reaction equal in size but not in direction.
True
Make a statement relating net force and balanced and unbalanced forces
Net fore if even leads to a balanced force and uneven net force leads to unbalanced forces.
To measure the inertia of an object you .
A) Measure Mass
B) Measure Force
C)Measure Velocity
A) Measure Mass
State Newton's 1st Law
Objects at rest remain at rest, and objects in motion remain in motion with the same velocity unless acted upon by an unballanced force
State Newton's 2nd Law
The 2nd Law states that the acceleration of an object increases with increased force and decreases with increased mass
State Newton's 3rd Law
The 3rd Law states that each action has an equal and opposite reaction
Define force and give 3 examples of it
Force is a push or pull (anything that is a push or a pull for examples works)
Define inertia
Inertia is an object's tendency to resist change in the speed or direction of its motion.
