forces and speed

Question 1

air resistance

Answer 1

the force on an object slowing it down when it moves through the air

Question 2

balanced forces

Answer 2

when forces are balanced the object is moving at a constant speed or not moving

Question 3

Answer 3

squash into a smaller space

Question 4

contact force

Answer 4

a force that acts upon an object when it is contact with air or water

Question 5

deform

Answer 5

to change shape

Question 6

drag force

Answer 6

a force that slows an object down when it is in contact with air or water

Question 7

push

Answer 7

the force of something moving an object away from it

Question 8

pull

Answer 8

the force of something moving an object towards it

Question 9

elastic limit

Answer 9

the point at which a spring will not go back to its original form when the force is removed

Question 10

Answer 10

the force acting between two charged objects

Question 11

equilibrium

Answer 11

balanced

Question 12

extension

Answer 12

the amount an object gets longer when a force is applied

Question 13

field

Answer 13

the region where something feels a force

Question 14

friction

Answer 14

the force that resists movement over a surface

Question 15

gravity

Answer 15

a non contact force that acts between two masses

Mass

Answer 20

the amount of matter something is made up of

Question 21

interaction pair

Answer 21

when two objects interact there is a force between them which is equal and opposite between them
