Kinematics
Change in position over time
What is velocity?
Unlike weight, this property of an object does not change regardless of its location in the universe.
What is mass?
This law states energy can neither be created nor destroyed
What is the Law of Conservation of Energy?
Change in momentum
What is impulse?
These are the three layers of the Earth
What are the crust, mantle, and core?
A sloped straight line on a velocity vs time graph
What is acceleration or changing velocity?
This Newton's law describes why a cannon moves backward when a cannonball is fired
What is Newton's 3rd Law?
This is the summation of the energy of motion and height.
What is mechanical energy?
While the force felt by both is equal, this specific value is significantly higher for a bug than for the bus it hit due to its size.
What is acceleration?
This is the largest desert in the world.
What is Antarctica?
Over the course of a day, a bug flies 10 m in 1 hour. It then travels 12 m in 1.5 hours to its next stop. Finally, it travels 13 m in 2.5 hours. What is the average speed of the bug?
What is 7 m/s?
These three forces change when the angle of a ramp changes
What are parallel (applied), perpendicular (normal), and friction forces?
This is the transfer of energy by a force acting on a 50 kg object as it is lifted 32 meters.
What is 15,680 J?
Crumple zones are effective because they increase this specific variable of an impact, thereby decreasing the force felt by passengers.
What is time?
This planet is closest in size to Earth
What is Venus?
This is the velocity of a quarter dropped from the top of the Eiffel Tower (312 meters tall) if there is no air resistance.
What is 78.2 m/s?
This change in velocity describes when a 7 kg object receives a net force of 35 N left.
What is 5 m/s/s?
This is the rate at which work is done to carry a 26.4 kg dog 2 meters in 8 seconds.
What is 64.68 Watts of power?
This many seconds of thrust are needed for a 60,000 N engine to change the velocity of a 120,000 kg craft by 5 m/s.
What is 10 seconds?
The number of bones in an adult human body
What are 206 bones?
This is how far a train car travels as it decelerates from 30 m/s to rest in 5 seconds.
What is 75 meters?
This is the coefficient of friction acting on a 8 kg sled that is being pulled with 20 N of force with a constant velocity.
What is 0.255?
A skateboarder approaches a ramp with a speed of 12.0 m/s. The total mass of the skateboarder and his board is 110 kg. The rider coasts up the ramp. Assuming no friction, at what height does the skateboarder come to a stop.
What is 7.35 meters?
In a perfectly inelastic collision, a 100 kg linebacker moving at 8 m/s hits a 100 kg running back moving at 2 m/s; they then move together at this shared velocity.
What is 5 m/s?
These are the four most common elements in the human body.
What are Carbon (18.5%), Hydrogen (9.5%), Nitrogen (3.3%) and Oxygen (65%)?
