1.  inert<u><em>i</em></u>a

2. dis<u><em>t</em></u>ance

3. displace<u><em>m</em></u>ent

4. f<u><em>o</em></u>rce

5. bala<u><em>n</em></u>ced

6. I think it's looking for 'velocity', but the clue is an incorrect definition.

7. motion

I'm surprised that you couldn't answer any of these.

Please don't use these answers from me to fill in the blanks on the sheet and then hand it in.  It's a mastery test, and you have not mastered this material.

Anarel [89]
S: 198 m 
v=39 m/s 
u=0
t=? 
a=?

v²=u²+2as
(39)²=(0)²+2(a)(198) 
1521=396a
1521/396=a
3.84 m/s^2 = a 

Hope I helped :)

What do work and energy have in common
spayn [35]

Energy and Work have the same unit of measurement which is Joules in SI units.

Explanation:

  • A Joule of Work is said to be done on an object when energy is transferred to that particular object.
  • If two objects are involved, when one object transfers energy onto the second, a joule of work is said to be done by the first object.  
  • Work is also the application of force on an object over a distance. So Work = Force × Displacement
  • Energy is neither created nor destroyed. It is in 2 forms - kinetic and potential.
  • Kinetic energy is defined as the energy of a moving object while potential energy is known as the energy that is stored within an object.
  • Kinetic Energy = 1/2 × mass × (velocity)²
  • Potential Energy = mass × acceleration due to gravity × height
  • Both energy and work are measured in Joules.
