Calculate
This is the weight of a 12 kg object on the moon where g is 1/6 of g on Earth.
What is 20 newtons?
Increasing the mass of an object while the net force remains constant will cause the acceleration to do this
What is decrease?
To double the acceleration of an object, this needs to be doubled as well.
What is the net force?
A skydiver opening their parachute increases the drag force by quickly changing this quantity.
What is cross-sectional area?
This major Boston highway is the longest interstate highway in the United States.
What is Interstate 90?
What is 40 newtons?
A person in an elevator feels heavier because the magnitude of this force increased.
What is the normal force?
An object is hung from a spring and the spring stretches some distance. Hanging an object that is twice as massive will cause the spring to stretch this far.
What is twice as far?
When you push on a car, it does not accelerate because this resists your push.
What is the force of static friction?
Who is Taylor Lautner?
A 1,000,000 kg train hits a stalled, empty 1000 kg car on the tracks and applies a force of 1,000,000 N to the car. The car applies a force of this magnitude to the train.
What is 1,000,000 newtons?
As the mass of an object increases, the coefficient of friction between the object and the floor does this.
What is stays the same?
An elevator car is held up by five identical vertical cables. If all but one of the cables are cut, the tension in the last cable attached has changed by this factor.
What is x5?
A person is standing on a bathroom scale in a stationary elevator. The person looks down at the scale as the elevator begins to move. The reading on the scale briefly increases, which means the elevator accelerated in this direction
What is up?
In December 2024, it took 11 days for this country's dictatorship to be ousted by rebels
What is Syria?
A 1000 kg car accelerates from 0 to 45 m/s in 3.0 s. If we assume the effects of drag are minimal, the magnitude of average net force experienced by the car is this.
What is 15,000 N?
An object is thrown straight upward. While the object is moving upward, the magnitude of the drag force does this.
What is decrease?
An object is suspended from a spring and the spring stretches some distance. Moving the contraption to the sun, where g is 28x g on Earth, will cause the spring to stretch this far.
What is twenty-eight times as far?
What is the force of gravity of the book pulling on the Earth?
This animal is the largest to have ever existed and the loudest
What is the blue whale?
The 5,557 kg Apollo 11 capsule entered Earth's atmosphere at a speed of approximately 11,000 m/s. The capsule slowed to a speed of 150 m/s while traveling a distance of 97 km, which means it experienced an average drag force of this magnitude.
What is 3,520,000 newtons?
A flat piece of paper is dropped and reaches terminal velocity when the drag force is equal to F1.
The piece of paper is crumpled and dropped and allowed to reach terminal velocity when the drag force is equal to F2.
This is a correct comparison between the magnitudes of F1 and F2.
What is F1 = F2?
Two cars are traveling at the same speed on a section of flat, level road. At the same time, they both stomp on the brakes as hard as possible. If one car stops in a distance of 100 m, the other car, which is twice as massive, will stop in this distance.
What is 100 m?
This force causes a car to speed up from a stoplight
What is the force of static friction?
Among the MBTA's subway lines, these are the only two that do not directly intersect
What are the red and blue lines?
