100

The SI unit of time

What is/are seconds?

100

A vector that describes how fast something is going

What is Velocity?

100

F = ma

What is Newton's 2nd law?

100

The formula for Momentum

What is p = mv?

100

The energy dependent on relative position

What is potential energy?

200

The number of grams in a kilogram

What is 1000?

200

The value that is 0 if you walk in a circle

What is Displacement?

200

Objects will not change velocity unless acted on by an outside force

What is inertia/1st law?

200

Momentum before and after a collision is the same

What is conservation of momentum?

200

The energy you would have at the bottom of a hill you sled down

What is kinetic energy?

300

The ratio you multiply a measurement by to change it's units

What is a Conversion Factor?

300

The slope of a velocity-time graph

What is acceleration?

300

Two forces that are equal and opposite, ala the 3rd law

What are action-reaction pairs?

300

This is EQUAL to change in momentum

What is impulse?

300

The reason a rollercoaster has smaller and smaller hills along the ride

What is friction?

Speed is lost due to friction and therefore the car will not make it over as high of a hill as it goes along.

400

kg * m/s^2 is equal to this unit

What are Newtons?

400

The name of the motion of thrown objects

What is projectile motion?

400

The reason an object can have 0 net force on it, but be moving at constant speed

What is.. acceleration being CHANGE in velocity?

No acceleration just means no increase/decrease in velocity.

400

A car collides with another and they drift off as a unit

What is an inelastic collision?

400

I drop a 2 kg object from a height of 10 m. Half way down, it has this much potential energy.

What is 100 J?

500

The unit I'd be converting to if I divide by about 750

What is Watts being converted to Horsepower?

500

Two balls. At the same time, one dropped down from a window, one thrown horizontally from the window.

Which ball has the greater speed at ground level?


What is NEITHER!

They both experience the same acceleration due to gravity in the vertical direction.

500

The force that allows a car to make a turn on the road

What is the force of friction?

500
Two objects of same mass have the same kinetic energy. Object 1 experiences a elastic collision. Object 2 experiences an inelastic collision. This object lost some KE.

What is Object 2?

500

This type of energy holds Na and Cl together to make salt
