F
What is force (double jeopardy!)
A push or pull that causes an object to accelerate
______ is a push or a pull
A _______ force does not move a object
Balanced
What force is present in this scenario? The force that keeps a female skater moving in a circle while being pulled by her partner
Centripetal Force
What is the change in position called?
Motion
Which force keeps us on earth?
Gravity Force
If centripetal force increases does acceleration also increase? (double jeopardy!)
Yes
How are balanced and unbalanced forces different? How are they the same?
Balanced forces don't move while unbalanced forces do, but they both have force or forces acting on a object
In a free body diagram what does long lines mean?
More force on the object
Name the law...an object at rest stays at rest, an object in motion stays in motion, unless outside forces act upon it
Newton's 1st Law
Name the law...F=ma
Newton's 2nd Law
What is net force?
A force that causes an object to move in a circular path
Centripetal Force
What is constant velocity?
Velocity that does not change over time
What is inertia? (double jeopardy)
The tendency of an object to stay at rest unless acted upon by an outside force
How does mass affect acceleration?
The heavier an object is the more force is needed to make it accelerate
What is acceleration?
Change in velocity over time
If the same force is applied to objects with different masses, which object will have greater acceleration?
The object with less mass
This scenario is related to which law of motion? A jellyfish applying downward force on the water (double jeopardy!)
Newton's 2nd Law
Name the law...for every action there is an equal and opposite reaction (double jeopardy!)
Newton's 3rd Law
A force that resists motion when two surfaces are pressed together
Friction Force
Is force a vector? (double jeopardy)
Yes, it has both magnitude and direction
