Newtons 1st Law
What is Newton's First Law also known as?
The Law of Inertia
What is a term for a push or pull?
Force
What is the Net Force when the same weight is being pulled from opposite sides?
0 Newtons
Stella and Callie are playing tug of war. Stella pulls 425N to the right, while Callie pulls 500N to the left. What is the Net Force?
75N to the left
True of False: Whenever something is moving it has momentum.
True
What word resists any change in motion?
Inertia
What force that causes an object to speed up, slow down, or change direction.
An unbalanced force
If an object has the same force on each side, what direction will the people go?
They won't move
A team pulls left in tug-of-war with 150 N, and the right team pulls with 100 N. Which way does the rope move?
To the left
Fill in the blank: Momentum is
Movement
If a textbook is flat on a desk, what forces can be acting on the book?
A balanced force with a Net Force of zero
What is the net force of an object when unbalanced forces are acting on it?
Not equal to zero
True of False: Balanced forces cause an object to change its motion or accelerate.
False
If Ella pulls with 200N to the left and Aubrey pulls 347N to the left, what is the Net Force?
547N to the left
When things crash, can they transfer momentum?
Yes
What are forces measured in?
Newtons
When unbalanced forces act on an object, the object will always experience this specific thing.
A change in motion
What are the two possible states of motion for an object experiencing balanced forces?
At rest or moving in a straight line
Fill in the blank: Net force is a combination of all of the forces on an object
Acting
True of False: Momentum depends on how fast something is going.
True
What is Newtons 1st Law?
An object at rest stays at rest, and an object in motion stays in motion at a constant speed and in a straight line, unless an outside force acts on it.
What law of motion says that an object will remain at rest or in uniform motion unless acted on by an unbalanced force?
Newtons 1st Law
For two opposite forces to be balanced, they have to have two relationships regarding their strength and direction. What are they?
Same strength and opposite directions
Two dogs are playing tug a war. Bailey is pulling 230N to the right while Chander is pulling 450N to the left. What is the Net Force?
220N to the left.
Does the faster something is going mean that it can transfer more momentum?
Yes
