100
This is the SI unit that measures time...
What is seconds?
100
This has no effect on the projectile if we assume constant velocity
What is the objects mass?
100
p stands for _____ and is measured in ______
What is position and meters?
100
Godzilla is fighting the hulk. The hulk body slams Godzilla in the chest. At the moment of impact, which monster will feel a greater force?
Who is neither! They feel the same force of impact.
100
I launch a projectile off a cliff horizontally at 50 m/s. How far does it travel (horizontally) after 3 seconds?
What is 150 meters (must have correct units)
200
The unit for mass!
What is a KILOgram?
200
Mass does have an effect on the motion of a projectile if this is kept constant.
What is the force behind the launch?
200
v stands for _______ and is measured in _______?
What is velocity and meters per second (m/s)?
200
What weighs more, a pound of feather or a pound of iron?
What is neither! They both weigh a pound!
200
I launch a projectile off a cliff at 50 m/s, how far (vertically) has it traveled after 3 seconds?
What is 45 meters?
300
This is what we use to measure how far something travels. A deestaughnce (distance) measurement.
What is meters?
300
45 degrees
What is the angle at which give the farthest launch range?
300
a stands for ________ and is measured in________
What is acceleration and meters per second squared (m/s^2)?
300
Newtons second law states F = m/a. What is wrong with this statement?
Its supposed to be F=ma
300
If a projectile needs 6 seconds to land, after being launched, how much time is needed for it to reach its maximum height?
What is 3 seconds?
400
The hulk, a very angry person, is jumping from building to building. If trying to predict where he is going to land we need the speed of his jump. How fast do you think the hulk can jump? (include your SI units)
What is approximately 268 meters/second?
400
Increasing this might not necessarily increase the range of the projectile
What is the angle of launch?
400
An object travels 30 meters in 5 seconds. What is its velocity?
What is 6 meters per second?
400
This law states that every action has an equal an opposite reaction. It is also known as the Law of Conservation of Forces.
What is the third law?
400
Whats the horizontal velocity of an object that has an initial velocity of 30 m/s at an angle of 60 degrees?
What is 15 m/s?
500
Newtons is the unit of measurement for...
What is force?
500
In an ideal situation, there is none of this present.
What is air resistance?
500
An object accelerates at 5 m/s^2. What is its speed after 5 seconds, given an initial velocity of zero?
What is 25 meters per second?
500
If an object has a force acting upon it, it must be doing this as well? (Moving is not the answer)
What is accelerating?
500
How far does an object travel (horizontally) given an initial speed of 10 m/s at 30 degrees?
