Speed
Speed is actually this
How fast something moves?
On a car this would be an accelerator
What are the gas pedal, brake, and steering wheel?
Two ways a force can be expressed
What is a push or a pull?
Sir Isaac Newton studied forces and was honored by this being named after him
What is the SI unit of force?
A car travels a distance of 500 meters in 10 seconds. Its speed would be
What is 50 m/s?
What is distance?
Slowing down is this type of acceleration
What is a negative acceleration?
2 forces combined will always have this
What is a net force?
Sir Isaac was really smart and successfully created this group of math principles while fleeing to the countryside hoping to avoid the Bubonic Plague.
What is Calculus?
A plane flight takes 2.55 hours. It has a speed of 250 km/h. The distance for the trip is
What is 638 m?
A second is the official measurement of time in this
What is SI, or System International?
The SI unit for acceleration.
What is m/s2?
A tug of war with one team winning is an example of this
What is an unbalanced force?
Sir Isaac was able to determine how to calculate this between any 2 universal objects as long as the masses of the 2 objects and the distance between the objects was known.
What is the Law of Universal Gravitation?
An ant travels 135 m and moves at a speed of 0.10 m/s to cover the distance. The journey takes the ant this long
What is 1,350 (1.4 x 103) s?
Velocity is similar to speed except it also includes this
What is direction?
A car speeding up with an acceleration of 5.0 units would be written this way
What is +5.0 m/s2?
Electrons move quickly, and are transferred easily, because they have a small amount of this
What is inertia?
Sir Issac is credited with many discoveries that after he tested his hypotheses he found that they were never contradicted. These are now known as
What are scientific laws?
A car slows from 27.0 m/s to a stop 4.00 seconds later. Its acceleration would be
What is -6.75 m/s2?
Displacement is calculated using this
What is a reference point?
Accelerations always include 2 of these
What are velocities?
A device on a car designed to spread out force during a sudden stop
What is a seat belt?
Sir Isaac studied motion and is credited with explaining how it works below light speed. The first begins "Objects in motion remain in motion . . . " it is also known as this
Newton's Law of Inertia
A racer takes 5.0 s to come to a stop with an acceleration of -1.5 m/s2. The initial velocity of this racer was
What is +7.5 m/s?
