Q

Air resistance/drag

A

Air resistance affects objects moving through the air slowing them down because of the particles hitting the object

16
Q

Resultant force

A

After an applied force has acted on an object the force that you are left with is the resultant force

17
Q

Interaction pairs

A

For every action there is an equal and opposite reaction

18
Q

Hooke’s law

A

Hookes law suggests that when an object is hanging every time a weights are added (equal mass) the extension of the spring will be the same as the one before

19
Q

Streamlined

A

Streamlined objects are objects that have a unique shape designed to smoothly move through air and water particles

20
Q

Newtons

A

Newtons are a type of measurement used to measure the amount of force acting on an object

21
Q

Balance force

A

Balanced forces are forces that are acting against each other however they have no effect because they are equal

22
Q

Newton meter

A

A newton meter is used to measure how many newtons are acting on an object

23
Q

Unbalanced force

A

An unbalanced force is a force that is being acted on however it is weaker thus has no effect

24
Q

Tension

A

Tension is a pulling force that acts on ropes etc

25
Q

Deform

A

If something is deformed then its shape has been changed from forces acting on it

26
Q

Weight

A

Weight is mass x gravity so on different planets and moons your weight will change!

27
Q

Three effects of forces

A

The three effects of forces are.

A force can move an object

A force can make an object accelerate

A force can make an object decelerate
