this is what happens after a bullet is shot out of the gun
The bullet will stay in motion until hitting an object, or falls to the ground due to air resistance and gravity explained in Newton’s first law of motion.
100
True or False: the arrow is straight when it is released from the bow
False, When a person releases an arrow, the arrow acts on the bow string and a large amount of force on the shaft of the arrow causing the arrow to shake back and forth spinning until it is straightened out.

true or false: bullet proof vests keep you from getting hurt, so you are indestructible.
false, you can actually get really hurt, since the bullet is so fast the impact can still really hurt you. they vest is just to stop the bullet from hitting your skin.

true or false: in the movies it is accurate when a person get thrown back after getting shot.
true

how does a gun work?
A gun works by using an explosive to project a missile the firing pin hits the primer and gas rushes out of the barrel of the gun bringing the bullet with it at high speeds.

Newton’s second law and equation
F=ma or a=f/m, The force of the string when it is released and the mass of the arrow give you the acceleration.

Ballistic Vest and Bullet Proof Vest
Stops bullet from penetrating by using strong layers of fiber to catch and spread the bullets force over a large portion of fibers, helping absorb impact.

Newton’s first law of Motion- Law of Inertia
What is An object at rest stays at rest while an object in motion with the same seed and the same direction unless acted on by an unbalanced force.
300
two types of bows: compound bow and the _______
What is longbow.
300
Hard-Plate Reinforced Vest
Increased protection by adding metal or ceramics for greater resistance to more powerful bullets, as well as protection from larger, sharper objects such as arrows, and knives.
300
two movies that are not accurately portrayed.
starship troopers, the matrix, die hard, and scarface
400
Newton's third Law
What is For every action there is an equal and opposite reaction.
400
how fast does a Compound bow and a long bow go.
185 feet per second is the long bow, and 300 feet per second for a compound bow.
400
What is Blunt force trauma?
A impact that affects a person internally without penetration.

How to find the velocity at impact with a target
What is Mass of bullet * Velocity of bullet = Mass of Target * Velocity of Target
