Mechanics

Question 1

What is displacement?

Answer 1

Displacement is the shortest route between two points

Question 2

What is position?

Answer 2

Position describes location relative to a fixed point

Question 3

What is speed?

Answer 3

Speed is the distance travelled over a period of time

Question 4

What is velocity?

Answer 4

Velocity is total displacement over a period of time

Question 5

What does it mean if there is straight, horizontal line in a displacement time graph?

Answer 5

No change in the displacement time graph means the object is stationary

Question 6

What does it mean when there is a straight, diagonal line in a displacement time graph?

Answer 6

Displacement increases at a constant rate when velocity is constant

Question 7

What does it mean when there is a curved line in a displacement time graph?

Answer 7

Displacement changes at a changing rate over time. Velocity is accelerating

Question 8

What is the equation for average velocity?

Answer 8

Total Displacement///Total Time

Question 9

What is the equation for average speed?

Answer 9

Total Distance///Total Time

Question 10

What is the SUVAT equation without ‘s’?

Answer 10

v = u + at

Question 11

What is the SUVAT equation without ‘v’?

Answer 11

s = ut + 1/2(at²)

Question 12

What is the SUVAT equation without ‘t’?

Answer 12

v² = u² + 2as

Question 13

What is the SUVAT equation without ‘a’?

Answer 13

s = 1/2(v+u)t

Question 14

What is the SUVAT equation without ‘u’?

Answer 14

s = vt - 1/2(at²)

Question 15

What is the value for acceleration in mechanics maths?

Answer 15

9.8m/s²
