Linear motion

Question 1

linear motion

Answer 1

motion in a straight or curved line with all body parts moving the same distance at the same speed in the same direction

Question 2

scalar quantity

Answer 2

when measurements are only described in terms of size and magnitude

Question 3

vector quantities

Answer 3

size/magnitude and direction

Question 4

mass v weight

Answer 4

mass - quantity off matter a body possesses.
weight - gravitational force on an object

Question 5

displacement v distance

Answer 5

displacement (vector) - shortest route in a straight line from start to finish
distance (scalar) - measures how much ground the body takes during its motion

Question 6

speed v velocity

Answer 6

speed (scalar) - movement per unit of time with no reference to direction
velocity (vector) - rate of change of displacement.

Question 7

acceleration

Answer 7

rate of change of velocity of an object.

Question 8

momentum

Answer 8

amount of motion a moving body possesses a
