• forces
• A force is a push or pull that is applied by one object on another
• Contact forces- the objects are physically touching such as a parachute in contact with the air
• magnets(fridge strips)
• tension( stretched elastic bands)
• Friction( heat generated)
• A scalar quantity has magnitude size only
• A vector quantity has magnitude and direction
• A vector quantity can be represented by an arrow, the length of the arrow represents the magnitude and the direction of the arrow shows its direction
• when we add vector quantities together we must consider the direction as well as the size
• The sum of two Vectors is known as the resultant
• Distance
• Distance is a measure of how the object has moved but doesn't indicate the direction it has moved in and is therefore a scalar quantity
• Scalars
• Mass
• Volume
• Speed
• Distance
• vectors
• Force
• Acceleration
• Velocity
• Weight
• displacement
• Acceleration
• Change in speed(m/s) / time taken(s)
• SUVAT Equations
• S-displacement
• U-initial velocity
• V-final velocity
• A-acceleration
• T-time
