Quick Tests Physics – Module 2
2
Simplify? Abstract Maths 2 Make the square the subject? 2 Find the triangle? 1) 2) 3)
3
Rearrange the following 10 equations to find “a” for each equation; Maths Maths rules Do the same to both sides i.e. add and divide Separate terms on one side must be put in brackets so each is dealt with the same Functions like cos, sin, tan, squares can be cancelled by their inverse. This is not the same as 1/x function Sqrt applies to everything not just the term you fancy Go one step at a time and write our your working, less chance of going wrong then! See if it is true for numbers at the start and end of your rearranging.

Vectors I NB. Ignore air resistance in all cases 1) What is the result distance and angle (from vertical); 2) What is the result force and angle (from horizontal); 4.123N 3) What are the resultant forces. 4) What is the resultant force NS and EW directions. Then resultant and angle?
5
Vectors II 1)vector or scalar? – force, temperature, acceleration, weight, displacement 2)When a ball is thrown vertically into the air what are the accelerating forces on it? 3)When a ball is thrown horizontally off a cliff what are the accelerating forces on it? 4)Draw a diagram and use Pythagoras rules involving cos & sin etc.. to explain how to resolve a resultant force into two forces at 90 degrees. 5)When dealing with a problem involving a picture frame hanging from a single wire under tension what can we say about the vertical or horizontal forces to help us solve the problem? 6)Explain the difference between displacement and distance travelled using the idea of a circular running track? NB. Ignore air resistance in all cases
