MECHANICS EXAMINATION TEST 2026
QUESTIONS WITH CORRECT ANSWERS
◉ Distance (d). Answer: it is the number of metres (m) between two
points or the metres travelled by an object
◉ Time (t). Answer: the number of seconds it takes for an event to occur
◉ Acceleration (a). Answer: the rate that speed changes for a moving
object, a change in speed : getting faster or slower (ms-2)
-is an increase in speed in a certain time
-can be calculated by dividing the change in speed by the change in
time, a=v/t
◉ Deceleration. Answer: a word used for 'slowing down' or 'negative
acceleration' (-ms-2)
-when describing in word answer NEVER say 'it is decelerating at -
10m/s2
-deceleration:write using positive value eg- decelerating at 10m/s2
-deceleration with a negative value: eg- accelerating at -10m/s2
, ◉ Mass (m). Answer: the quantity of matter in an object measured in
kilograms (kg)
◉ Weight force. Answer: is a force measured in Newtons and it is the
force due to gravity. Fw=mg
◉ Work (w). Answer: is the energy transferred from one form to another
and is work is done whenever an object moves in the direction of the
force that is being applied to it, measured in joules (J)
-If you are carrying something "along" there are NO forces acting on it
in the direction of motion (no change in speed so no change in energy)
so no work is done.
◉ Power (P). Answer: the rate at which work is being done measured in
Watts (W)
-work done per second
-A more powerful person/thing does more work in the same time or the
same work in less time
◉ Pressure (P). Answer: pressure depends on the amount of force used
and how big an area of force is spread over or force applied to a certain
area measured in (Nm-2) or Pascals (Pa)
-is force per unit area
-To turn cm2 into m2 divide by 10,000 (100 x 100) 10^-3
