As the force exerted on the projectile is
equal to the mass of the counterweight times the gravitational constant
, when the mass is increased, the force will also increase.
How does the potential energy used by the counterweight as it drops relate to the kinetic energy of the projectile as the projectile is launched?
The potential energy from the raised counterweight is transformed into kinetic energy—the energy of motion—as the counterweight is released and begins to fall. The downward motion of the counterweight then causes the
sling
to swing and the projectile to be released.
How does adding mass to the counterweight of a trebuchet affect the amount of potential energy of the counterweight?
From this equation it is clear that the greater the gravitational potential energy of the counterweight – therefore the greater the mass of the counterweight m1, and the greater the height to
which it is raised/ falls through h
, and the smaller the mass of the projectile, m2, the greater the initial velocity of the …
How does changing the projectile mass affect your trebuchet performance?
A larger counterweight mass makes the projectile#s
end go faster
, therefore throwing the projectile further, the average distance was 4.4 meters. … So a trebuchet with a long arm and a heavy counter weight will throw a projectile further then a trebuchet with a short arm and a light counter weight.
When a trebuchet counterweight is hoisted by soldiers what form of energy is transferred into the machine as work?
When soldiers use their energy to hoist the trebuchet counterweight, the potential energy stored in the counter weight converts to
kinetic energy
of the counterweight as it is released and falls.
What is the best ratio for a trebuchet?
General advice is that the optimal ratio is
133:1
. A golf ball projectile (1.62 oz) should fire best with 13.46 lbs of counterweight – and a 14 lb bowling ball should have 1862 lbs pulling on the other side of the arm to reach maximum distance.
What class of people compelled garrisons to surrender?
It was
the engineers
, men of really quite low social status in comparison, with the great siege engines. It was they who compelled the garrisons to surrender.
How does a trebuchet release the projectile?
To launch a projectile, a trebuchet
utilizes the transfer of gravitational potential energy into kinetic energy
. A massive counterweight at one end of a lever falls because of gravity, causing the other end of the lever to rise and release a projectile from a sling.
What factors affect how far a projectile will land?
- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.
Does mass affect range of projectile?
Explanation:
Mass is not relevant in projectile motion
. What is relevant is the initial speed and direction of the object.
How does the angle of release of the projectile affect the range?
Answer: C Explanation: The maximum range occurs for a launch angle of 45°. … This
highest point increases as the angle increases
. At a 75° launch angle, the maximum height is approximately 76 meters. However, a further increase in launch angle beyond this 75° angle will increase the peak height even more.
How much weight can a trebuchet throw?
A trebuchet is a device for attacking fortifications. Roughly speaking, a trebuchet has a few advantages over a catapult. First, it can handle heavier projectiles. A catapult’s maximum weight tops out at about 180 pounds; trebuchets top out
at about 350.
Are trebuchets still used?
While they are no longer used in warfare,
today people still build trebuchets for fun and use them in contests to see who can launch things the farthest
. There are many different factors that can affect the range of a trebuchet; for example, the mass of the counterweight or the length of the lever arm.
How is lifting a counterweight considered doing work?
As the counterweight falls through the height h, its gravitational potential energy is converted to the kinetic energy of the missile; its energy due to its motion, and the gravitational potential energy of the missile; the work done to
raise it up from the ground against the force of gravity
.
What types of energy is used to make a trebuchet work?
For a trebuchet, the
potential energy is gravitational
. This energy results from the force put in as the muscular push or pull needed to lift up the end of the lever with the heavy counter weight.
What forces are at work in a catapult?
A catapult is a launching device that allows us to experimentally observe projectile motion (see Figure 1). Once the ball is launched, the only forces acting are
gravity and air resistance
.
