Torque 0

Torque

Torque (moment) results from a force that causes an object to turn about an axis, fulcrum or pivot. Torque is given by: τ = rF Where r = distance from the pivot point, and...

Centre of Mass 0

Centre of Mass

Is the point around which all of its mass is evenly distributed For motion, we assume that all mass is condensed at this point It is the point about which a free body rotates...

Satellites 0

Satellites

Can be categorised as natural or man-made When a satellite is in orbit, the centripetal force is provided by gravity The gravitational force causes the satellites to fall continuously towards the Earth However, it...

Gravitational Fields 0

Gravitational Fields

Aim: Describe and interpret radial gravitational field distribution around a single point mass Explain and apply Newton’s Law of Universal Gravitation and the concept of gravitational acceleration, g, as gravitational field strength Explain the...

Vertical Plane 0

Vertical Plane

When objects are rotated on a vertical place, they feel both W and N. The sum of these forces is equal to the centripetal force (this is common to all circular motion problems). The...

Banked Turns 0

Banked Turns

Allow vehicles to go around a circuit faster than unbanked curves Reduces the reliance on tyre friction, since gravity provides some of that force Sum of forces is equal to the centripetal force Design...

Circular Motion 0

Circular Motion

Aim: Explain and apply the concepts of centripetal acceleration and centripetal force as applied to uniform horizontal circular motion and vertical circular motion, including applying the relationships: Circular Motion When an object moves around...

Projectile Motion 0

Projectile Motion

Aim: describe and apply the concepts of distance and displacement, speed and velocity, acceleration and energy in the context of motion in a plane, including the trajectories of projectiles in the absence of air...

Scalar and Vector Quantities 0

Scalar and Vector Quantities

Aim: Resolve, add and subtract vectors in one plane A scalar is any quantity with a magnitude, but no direction. A vector is any quantity with both magnitude and direction. Vectors can be represented...
