What happens to frictional force when a change in speed occurs?
The faster an object moves through a fluid, the greater the frictional force which acts on it
1 of 7
What will happen to an object falling through fluid?
An object falling through fluid will initially accelerate due to the force of gravity, eventually the resultant force will be 0 and the object will move at its terminal velocity (steady speed)
2 of 7
What is the relationship between weigh, mass and gravitational field strength?
Weight = Mass x Gravitational Field Strength
3 of 7
How may the shape of an object be changed?
A force acting on an object may cause a change in the object's shape
4 of 7
What is meant by an object that is behaving elastically?
An object is said to behave elastically if it returns to its original shape when a force is removed
5 of 7
What happens when a force is applied to an object like a spring?
A force applied to an elastic object like a spring will cause it to stretch and store elastic potential energy

What is the relationship between force and extension? (where k is a constant)
Force = k x Extension (i.e the extension is directly proportional to the force applied, providing the limit of proportionality is not exceeded)
