Flashcards in Forces And Motion Yr 10 -1 Deck (17):
1

Bouncing ball 3rd law

Ball bouncing on floor creates action force and reaction force is floor pushing back on ball

2

Swimming 3rd law

Force of feet and hands pushing on water creates a action force

3

Weight and mass

Weight = mass x9.8

4

Distance

Length of total path travelled

5

Displacement

Length of direct line from start to finish

6

Scalar quantities eg and what

Speed, time distance
Quantities with magnitude

7

Vector quantities

Displacement , acceleration, force

Quantities with magnitude and direction

8

Speed

Distance traveled per unti time

9

Velocity

Displacement per unit time

10

Acceleration

When an object changes its velocity

11

Systematic erro

Equipment not assembled properly
Change in conditions

12

Random error

Measurement differs from actual value

13

Finding displacement in velocity time graph

AREA

14

Force

Interaction between 2 bodies that causes a change in motion

15

Newton's first law

A body will remain at rest or co to ur moving with consistent velocity when the total force acting on it is zero

16

3rd law walking

Person pushing on floor causes the action force and friction between them causes the reaction force which allows waking

17

Second law of motion

A body will accelerate in the direction of the total force acting on it
