General Motion/SUVAT

Question 1

Translation =

Answer 1

Object moving A to B.

Measured in m/cm/mm.

Question 2

Rotation =

Answer 2

Body moves around its centre of mass.

Measured in degrees/radians/rotations.

Question 3

Scalar =

Answer 3

Only has a magnitude (size).

Examples - distance/speed/time.

Question 4

Vector =

Answer 4

Has a magnitude and direction.

Examples - displacement/velocity/acceleration.

Question 5

Distance can be defined as the exact path that has been travelled (e.g. 200m). Is this a scalar or vector quantity?

Answer 5

Scalar.

Question 6

Displacement can be defined as a direct path/change in position from A to B (independent from the path). Is this a scalar or vector quantity?

Answer 6

Vector.

Question 7

What is the equation to work out velocity?

Answer 7

Velocity = change in position (displacement) / change in time

Question 8

What is the equation to work out acceleration?

Answer 8

Acceleration = change in velocity / change in time

Question 9

What are the units for velocity?

Answer 9

m/s or m.s^-1

Question 10

What are the units for acceleration?

Answer 10

m/s/s or m.s^-2

Question 11

When athletes are airborne, what is their acceleration?

Answer 11

Acceleration due to gravity (g/9.81 m/s/s)

Question 12

List the 4 SUVAT equations.

Answer 12

v = u + at
s = 1/2(u + v) t
s= ut + 1/2at^2
v^2 = u^2 + 2as
