Newton's Three Laws of Motion

1. An object at rest will remain at rest, or an object moving at a constant velocity will remain moving at a constant velocity, unless acted upon by an unbalanced force (Net Force).

i.e. Only an unbalanced force (net force) can change an object's velocity (accelerate)

2. Net force = mass x acceleration

Fnet = ma

Fnet : Sum of all the forces - unit Newton (N)

m : Mass - unit kilogram (kg)

a : Acceleration - unit meter persecond squared (ms-2 )

3. Every action has an opposite and equal reaction on the other object

Newton's Three Laws of Motion

Newton's second Law F=ma

Velocity - Distance - Time

• Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s or (ms-1)
• Distance is a length. SI unit: meters (m)
• Time is needed for things to change. SI unit: second (s)

Acceleration - Velocity - Time

• Acceleration is a change of speed (velocity) per unit time. SI unit: meters per second per second or meters per second squared (ms-2)
• Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s or ms-1)
• Time is needed for things to change. SI unit: second (s)

Plans for making a Trebuchet & Catapult

Designing a Trebuchet – Optimizing Weight and Length

Cam's Trebuchet

Optimisation of Trebuchet:

1. The length of the payload arm should be 3.75 times longer than the counterweight arm.
2. The length of the sling should be the same length as thepayload arm.
3. The initial angle between the counterweight arm and the support should be 45 degrees at launch.
4. The counterweight needs to be 133 times as heavy as your intended projectile.
