Motion & Energy
What is kinetic energy?
The energy an object has because of its motion.
The ability of a material able to return to its original position after being stretched or compressed is called...?
Elastic Force
What is gravitational force?
A pulling force exerted by any object that has mass, the more mass the stronger the pull of gravity.
The result of all the forces on an object
Net Force
Who's the tallest in our A-period class?
Osazuwa
SGPB
Look at your teacher, assuming they're not moving, what kind of energy do they have?
Potential energy
A ball rolling in grass begins to slow down and eventually stops, this is an example of...?
Frictional force.
Definition - A contact force exerted by a surface as an object moves across it or makes an effort to move across it. Results from the two surfaces being pressed together closely.
A volleyball is falling, what force is pulling it down?
Gravitational force
F=M x A
Newton's second law
Who's your favorite superhero?
The only right answer is Batman
The distance an object travels in a given amount of time is...?
Speed
A contact force that is transmitted through a string, rope, cable, or wire when it is pulled tight by forces acting from opposite ends.
Two magnets with opposite pole orientations will be pulled towards each other, this is an example of...?
Magnetic force
Kahleb is pushing against the table with 70N of force, and Justin is pushing against the table with 150N of force, what is the net force?
80N
Why is Justin mad all the time?
Because that's how he is..?
Vividly imagine pushing the person next to you, what would that be considered?
Energy transformation
(Potential to kinetic energy)
A boulder getting pushed around by the person next to you, what is this an example of?
Applied force
The attraction or repulsion between electrically charged particles because of their motion.
Electromagnetic force
If you get in a car crash, why would you continue moving forwards after the car stops?
Newton's first law, inertia.
What is Mrs. Fraine's middle name?
Fleury
If you eat a burger, would the energy from the burger be destroyed? Why?
No because of the law of conservation of energy, which is energy can neither be created nor destroyed - only converted from one form of energy
The support force exerted upon an object that is in contact with another stable object.
What is a Normal Force?
If you are riding on a rollercoaster and it goes in a loop-de-loop, what kind of force would be acting on it?
Centripetal force
What is Newton's 3rd Law?
Every action has an equal and opposite reaction, this means that if you punch a wall, the wall will punch back with an equal amount of force.
What is Mrs. Fraine's new son's name?
Calvin Fraine!!
