Edexcel GCSE Combined Science CP15 Forces and matter overview quiz quiz

The force applied to a spring is inversely proportional to its extension, so a bigger force gives a smaller stretch

The extension of a spring stays the same no matter how much force is applied to it

The extension of a spring is directly proportional to the force applied (up to the limit of proportionality)

The force on a spring is equal to its mass multiplied by its acceleration

F = ma

F = mv

F = IR

F = ke

40 N/m

2.5 N/m

0.025 N/m

10.25 N/m

The object stays permanently deformed even after the force is taken away

The object returns to its original shape when the force is removed

The object snaps and breaks apart when the force is applied

The object becomes denser as it is squashed

The object springs straight back to its original shape once the force is removed

The object always shatters into pieces when stretched

The object does not return to its original shape after the force is removed

The object cools down as it is deformed

The point at which the spring snaps and breaks completely under the load

The original unstretched length of the spring before any force is applied

The largest force a spring is able to hold without moving

The point beyond which extension is no longer proportional to the force

A straight line through the origin

A curve that bends away from the start

A flat horizontal line across the graph

A closed circular loop

The increase in length compared with the original length

The total length of the spring once it has been stretched out

The mass of the spring measured in kilograms

The weight of the load added to the spring

It is weaker and much easier to stretch out

It is stiffer (harder to stretch)

It is longer when it is unstretched

It has a greater mass and weight
