Wind
The force that slows objects down as they collide with air particles
What is "Air Resistance"?
A free-body diagram shows _____ on an object due to contact.
What is "Force"?
This factor or variable has the largest effect on kinetic energy
What is "Speed"?
From our cart & box lab/simulation, which object would best represent a wide receiver (the person catching a football)?
What is "the box"?
Other than speed and mass, name two other factors or variables that cause damage in a collision
What is "Shape, Material, Distance/Height, Protective Covering, or Size"?
When wind speed against an object increases, what happens to the air resistance forces?
What is "The air resistance forces increase"?
Which pitch has the most kinetic energy?
What is "Pitch A"?
Decreasing the speed or mass does this to kinetic energy.
What is "Decreases"?
Which types of forces would be seen by a car traveling on a bumpy road?
What is "Air resistance AND friction"?
What is kinetic energy?
What is "Energy an object has because it is moving"?
What happens to an object's speed when air resistance increases?
What is "It decreases"?
Which pitch has the most air resistance?
What is "Pitch C"?
Increasing the mass by 4 times the original amount means the object will have this much kinetic energy.
What is "4 times"?
From our cart & box lab/simulation, which object would best represent a quarterback (the person throwing a football)?
What is "the launcher/push-pull spring scale"?
Karate chopping a wood board is an example of this type of collision
What is "Type B"?
How does changing a headwind to a tailwind affect the amount of kinetic energy an object has?
What is "The object will have more kinetic energy"?
Which ball has the highest final pitch speed?
What is "Pitch A"?
Increasing the speed by 5 times the original amount means the object will have this much kinetic energy.
What is "25 times"?
What is this an example of?
What is "Potential Energy"?
This causes a change in motion.
What is "Energy"?
What happens to kinetic energy on a particle-level when air resistance comes into contact with an object?
What is "the particles in the air collide with the particles of the object, and the energy is transferred from the object to the air"?
How would the arrows on a free-body diagram differ between an object with low peak force and an object with high peak force?
What is "the object with low peak force would have smaller, shorter arrows facing it while the object with high peak force would have larger, longer arrows"?
Speed have more of an effect than mass on kinetic energy because this needs to be done.
What is "Speed needs to be squared"?
Marco throws a water balloon at his friend and it pops. What happened to the water balloon right before it popped? (think about what the object reached with its force)
What is "Friction"?
