Forces And Motion Yr 10 -1

Question 1

Bouncing ball 3rd law

Answer 1

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

Question 2

Swimming 3rd law

Answer 2

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

Question 3

Weight and mass

Answer 3

Weight = mass x9.8

Question 4

Answer 6

Speed, time distance

Quantities with magnitude

Question 7

Vector quantities

Answer 7

Displacement , acceleration, force

Quantities with magnitude and direction

Question 8

Speed

Answer 8

Distance traveled per unti time

Question 9

Velocity

Answer 9

Displacement per unit time

Question 10

Acceleration

Answer 10

When an object changes its velocity

Question 11

Systematic erro

Answer 11

Equipment not assembled properly

Change in conditions

Question 12

Random error

Answer 12

Measurement differs from actual value

Question 13

Finding displacement in velocity time graph

Answer 13

AREA

Question 14

Force

Answer 14

Interaction between 2 bodies that causes a change in motion

Question 15

Newton’s first law

Answer 15

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

Question 16

3rd law walking

Answer 16

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

Question 17

Second law of motion

Answer 17

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