The ONLY time a position-time, velocity-time, and acceleration-time graphs are identical.
What is when an object is at rest?
A ball is thrown straight up with a velocity of 5 m/s. The velocity of the ball at the top of the path is this.
What is 0 m/s?
A 3 kg wig sits on a 12 kg mannequin head which are in a display case. This is the combined weight of the wig and head.
What is 150 N?
The unit for force is the Newton which is named after Sir Isaac Newton. The Newton is actually a combination of base units, such as meters and kilograms. Broken out and written in its base units, the N is this.
kg m/s2
The Law of conservation of Energy says that energy in a system is neither created nor lost, however, energy can be transferred out of a system. Energy transferred out of a system in the form of thermal energy is due to this force.
What is friction?
Also the protagonist in the first full-length animated movie, she is the original Disney Princess.
Who is Snow White?
The object is at rest during this time segment.
What is between 2 and 3 seconds?
An out-of-shape runner leaves his house. First he runs 500 m West, then 200 m South, decides to come back and runs 500 m East, before giving up and hopping in a cab which takes him the rest of the way home. The cab drives this far.
What is 200m?
A bowl of grapefruits sits on a dinner table and experiences a normal force of 15 N. This the mass of the bowl.
What is 1.5 kg?
There are many laws in physics, but of the ones we've discussed so far, this one can be stated as the equations Fnet = ma.
What is Newton's 2nd Law?
Energy is never conserved, but momentum is conserved in this type of collision.
What is an inelastic collision?
Over the weekend, two NFL teams played in London, England. The broadcast was done in a VR-style presentation that took place in Andy's room and included many Toy Story characters. These two teams were involved.
Who are the Atlanta Falcons and the Jacksonville Jaguars?
This is the slope of a velocity-time graph for an object in free fall (falling while only experiencing gravity).
What is -9.8 m/s2 or -10 m/s2?
Olympic speed skating takes place on an oval track where athletes start and stop at the same point of a track of approximately 110m. After taking 90 seconds to skate 9 complete laps, this the skater's average velocity.
What is zero? (The displacement is zero, so the average velocity is zero.)
In order to keep an airplane cruising at a constant velocity, engines provide thrust which cancels out the air resistance the plane experiences. The plane also needs lift to cancel out the gravitational force on the plane. This law explains how he balanced forces create the constant motion.
What is Newton's 1st Law?
It is the equivalent of one-tenth of a meter.
Decimeter
A runaway garbage can of 50 kg is sliding across the sidewalk at 8 m/s and headed straight for Evelyn. She applies a force of 80 N to stop it. How long does she need to apply this force in order to stop the can?
What is 5 s ?
One of the most important speeches in US history, Martin Luther King told crowds of people that "I have a Dream" at this national landmark.
What is the Lincoln Memorial?
The graph shows the motion of a bug moving in a straight line. The bug has the greatest speed during this time segment.
What is C?
Captain America punches a bad guy (any villain of choice is ok.) His fist is 15 kg and was initially moving at 30 m/s as it strikes the villain's face. This acceleration brought his fist to rest in 0.5 s.
What is 60 m/s2?
One trucker slides a 40 kg box of red cabbages across the truck floor towards another trucker. As the box slides between them, the box experiences a friction force, normal force, and gravitational force. This is a Newton's 3rd Law pair associated with the box as it slides.
What is the box/earth gravity pair; box/floor friction pair; or box/floor friction pair?
An acceleration can be one or more of these three changes in motion.
What is speeding up, slowing down, and/or changing direction?
Two identical cars drive side-by-side down the highway when a buffalo comes running down the middle of the road. They both swerve to avoid the beast. Car A hits a concrete median. Car B hits a yellow crash cushion on the side of the road. Both cars stop. This can be said about the impulse on the two cars.
What is "they are the same"?
Prep, learn, and practice.
A big test is coming soon.
This review will help.
A haiku contains this many syllables in each line.
What is 5, 7, 5?
An interior designer is rearranging a room and the velocity-time graph shows the motion of a couch. After the 4 seconds shows, the couch is now this far from where it began. (The magnitude of displacement)
What is 1.5 m away?
The sky is falling, or maybe its just a rain drop. If the rain drop has fallen for 10 s, it has traveled this far.
What is 500 m?
A cashier at a grocery store pushes a 10 N container of peanut butter to the bagger. As it slides, it experiences a frictional force of 3 N. The cashier applied THIS much force to give the peanut butter a net force of 4N, .
What is 7 N?
A student decides to up his shot put game in an effort to become state champion. Taking into account the physics concepts he learned in class, he decides to launch the heavy orb at this angle to achieve maximum range.
What is 45 degrees?
A 5 kg rock falls off a 20 m cliff. It has this much kinetic energy when it is 4 m off the ground.
What is 800 J ?
You can spend a lot of money on super fancy TVs and monitors. 4k refers to the resolution of the display. OLED stands for Organic Light Emitting Diode. LCD stands for this.
What is Liquid Crystal Display?
