We measure an object's weight with this.
What is a spring scale?

This person is believed to have tossed two cannonballs with different masses off the Leaning Tower of Pisa.
Who was Galileo?
200
This is what Aristotle believed would occur if two objects with different masses were dropped from the same height.
What is hit the ground at the same time?
200
This is the numeric value of acceleration due to gravity on Earth.
What is 9.8 m/s^2?
200
The resistance of objects to change their motion (or non-motion).
What is inertia?
200
The flat surface of the triple beam balance where objects are placed to determine their mass.
What is the pan?
300
There are three of these on a triple beam balance. They slide left to right.
What are riders?
300
Although free fall does not truly exist on Earth, give an example that is "close" to free fall.
What is jumping out of an airplane, dropping from a roller coaster, space shot at Adventureland, others?
300
As an object falls to Earth, it accelerates until it reaches _________ and continues at a constant speed.
What is terminal velocity?
300
The force that resists motion in the air.
What is air resistance?
300
The two components of projectile motion.
What is horizontal and vertical motion?
400
An object at rest stays at rest and an object in motion stays in motion unless an outside force acts upon them.
What is Newton's First Law of Motion?
400
What is the force that attracts objects to each other?
What is gravity?
400
An object of greater mass needs a ________ force to accelerate it than an object of lesser mass.
What is greater?
400
If a greater force is exerted on an object, what will happen to its acceleration?
What is it will increase?
400
Why would two items of different masses dropped from the same height land at different times?
What is the items are dropped in different gravitational conditions?
500
A rock at rest falls off a tall cliff and hits the valley below after 3.5s. What is the rock's velocity as it hits the ground?
What is 34.3 m/s?
500
Which would land first? A penny dropped straight down or a penny put in projectile motion assuming they start at the same height and same velocity.
What is they would land at the same time?
500
As two objects with different masses are dropped from the same height and at the same initial velocity, the extra mass of one object exactly balances out the greater gravitational force needed by that object and thus both objects do this.
What is accelerate to Earth at the same time.
500
What does the triangle mean in mathematical formulas?
