forces and motion

Question 1

what is a force

Answer 1

a push or pull in a particular direction

Question 2

what are the 2 forces

Answer 2

contact and non contact

Question 3

give 3 ex of contact forces

Answer 3

pushing a block kicking a soccer ball writing with a pencil

Question 4

what scientific laws

Answer 4

description of what occurs in nature

Question 5

what are scientific theory

Answer 5

explanation for why or how something occurs in nature

Question 6

3 ex of non contact forces

Answer 6

gravitational magnetic electrostatic

Question 7

describe 3 things forces have the ability to do to an object

Answer 7

make an object move, stop a moving object, change the speed of a moving object

Question 8

record the unit and equation for measuring force

Answer 8

newtons
f=mass(kg) x acceleration(mps2)

Question 9

what is electrostatic force and how does it occur

Answer 9

the force that exists between electrically charged particles between 2 objects

Question 10

what are magnetic forces and how do they occur

Answer 10

a force that attracts or repels magnetic objects
its a push or pull exerted by a magnet

Question 11

what is gravitational force? where does gravity pull objects

Answer 11

the force by which an object attracts another object towards itself

Question 12

when does motion occur

Answer 12

when an object changes its position relative to a reference point

Question 13

discern between distance and displacement

Answer 13

how far an object has traveled
distance+direction of an objects change in position from starting point

Question 14

give an ex of distance

Answer 14

walking to somebodies house

Question 15

give ex of displacement

Answer 15

stoping half way to eat a sandwich

Question 16

what is speed? how is it diff to velocity

Answer 16

distance an object travels per unit of time
v takes direction into account

Question 17

what is acceleration

Answer 17

rate of change in velocity

Question 18

what are the 3 types of speed

Answer 18

instantaneous, avg speed, constant

Question 19

give ex of each type of speed

Answer 19

checking speedometer, taking road trip, cruise control

Question 20

what is equation for speed

Answer 20

s(meters per sec)= d(meters)/t(secs)

Question 21

what is equation for acceleration

Answer 21

vf-vs/t

Question 22

whats momentum? definition

Answer 22

property of a moving object resulting from its mass + velocity

Question 23

whats inertia

Answer 23

tendency of an object to resist any change in its motion

Question 24

what are the 3 laws of motion? def and nickname

Answer 24

inertia- an object in motion stays in motion or an object at rest stays at rest until an unbalanced force acts upon it
acceleration- a net force acting on an object cause the object to accelerate in the same direction as the force
action and reaction- for every action or force there is an = opposite reaction or force
