Forces
Potpourri
100
the tendency of all objects to resist a change in motion
What is Inertia?
100
9.8 m/s/s or 9.8 m/s2
What is the rate of acceleration of all objects near Earth's surface
100
The third Law (state it)
What is "for every action, there is an equal and opposite reaction"?
100
A push or a pull
What is force
100
He believed that the rate at which an object falls depends on its mass
Who is Aristotle?
200
Inertia is affected by this property
What is mass?
200
The formula for Second Law
What is F=ma?
200
the curved path of an object; involves two components-horizontal and vertical motion
What is projectile motion?
200
This is the attractive Force between any two masses
What is Gravity
200
This type of motion is a combination of forward motion and free fall
What is orbital motion? (an orbit)
300
This causes a change in motion
What is a force
300
A clown throws a cream pie (500 g) at an acrobat with 10 N of force. At the same time the acrobat throws an apple pie (1 Kg) at the clown with 10 N of force. Which person has more time to dodge the incoming pie.
What is the clown
300
Examples of Newton's third law
What is a rocket launch, releasing the air in a balloon, Newton's cradle etc
300
The unit of measure for force
What is newtons
300
Mass and velocity determine this property of matter; as one or both increase, THIS increases as well
What is Momentum
400
An object at rest will remain at rest and an object in motion will remain in motion until an unbalanced force acts on them
What is Newton's First Law?
400
A book with a mass of 2 kg is pushed along a table. If the net force on the book is 1 N, this is the book's acceleration.
What is 0.5 m/s/s
400
A volleyball player spikes the ball with 100 N of force. This is the amount of force that she feels.
What is 100 N
400
This force opposes the force of gravity to slow objects down when moving through the air
What is air resistance?
400
The rate of change in velocity
What is acceleration
500
A magician pulls a tablecloth off of a table containing a 5 kg crystal ball, a 1 kg vase and a 200 g magic wand. This item is most likely to stay on the table. Why?
What is the 5 kg crystal ball. Because objects with greater mass are more resistant to a change in motion
500
This amount of force is required to accelerate a 100 kg object at 10 m/s/s
What is 1000N?
500
Forces are always found like this
What are pairs
500
The unbalanced force that causes objects to move in a circular motion.
What is centripetal force?
500
the constant velocity of a falling object when the force of gravity is balanced/equal to the force of air resistance
What is terminal velocity?
