The magnitude of velocity is the object's speed. Velocity - Velocity is the rate of change in an object's position.

Vector - A vector is a quantity that has both a magnitude and a direction. Third law of motion - The third law of motion states that for every action there is an equal and opposite reaction. It is a scalar quantity measured by distance over time. Speed - Speed is the measurement of how fast on object moves relative to a reference point. Some examples of simple machines include the lever, pulley, inclined plane, wedge, and screw. Simple machine - A simple machine is a basic mechanical device for applying a force and doing work. Second law of motion - The second law of motion states that the greater the mass of an object, the more force it will take to accelerate the object. Unlike a vector, a scalar does not have direction. Scalar - A scalar is a measurement that only measures the magnitude. Pressure - Pressure is the force over a given area. Power is calculated by dividing work over time. Power - Power is a measurement of the rate at which energy is used. Potential energy - Potential energy is the energy stored by an object due to its state or position. Pascal - The pascal is the standard unit of measure for pressure. Newton - The newton is the standard unit of measure for force. It is a vector measured in newton-seconds. Momentum is equal to the mass times the velocity of an object. Momentum - Momentum is a measurement of mass in motion. Mass - Mass is a measurement of how much matter is in an object. It is a scalar quantity calculated using the formula KE = ½ * m * v 2, where m = mass and v = velocity. Kinetic energy - Kinetic energy is the energy an object has due to its motion. Joule - The joule is the standard unit of measure for energy and work.

Impulse - An impulse is a change in momentum. On Earth gravity pulls at objects with an acceleration of 9.8 m/s 2. Gravity - Gravity is a force caused when the mass of physical bodies attract each other.

It is a force and is measured in newtons. Force is a vector measured in newtons.įriction - Friction is the resistance of motion when one object rubs against another. The standard unit of measure for energy is the joule.įirst law of motion - The first law of motion states that any object in motion will continue to move in the same direction and speed unless external forces act on it.įorce - Force is the measurement of a push or pull on an object. It is a vector quantity.Įnergy - Energy is the ability to do work. Acceleration is a vector.Ĭollision - A collision in physics occurs when any two objects bump into each other.ĭisplacement - In physics, displacement refers to an object's overall change in position. It is equal to the change in velocity over the change in time. In the event that no one is available, the parcel will be taken to your local depot and a note will be left with instructions for redelivery.Acceleration - Acceleration is the measurement of the change in an object's velocity. Most items will require a signature on delivery. Small items are usually sent by Royal Mail 24, whilst larger or more expensive items are sent with DPD. If you require Saturday delivery there will be an additional charge, please give us a call for a quote. All orders are dispatched using a next working day delivery service. Orders below £50 are subject to a £1.95 delivery charge. Northern Ireland, Highlands and Islands will take 2 working days. *Mainland UK addresses only, excludes bank holidays. Please order in as early as possible to avoid disappointment.įree Next Working Day Delivery on all orders over £50, placed before 3pm, Monday to Friday. We will be doing everything we can to minimise disruption, but delays will be inevitable. Increased pressure on our other couriers may also cause delays due to the increased volume of parcels in their networks. Items posted the day before, during or in the days after any strike action are likely to be subject to delays. Royal Mail will be striking on the 26th and 31st August and the 8th and 9th September 2022.
