Ch.3 & 4 Study Guide ( Integrated Science)

Front 1

Motion

Back 1

Change in position

Front 2

Displacement

Back 2

distance and direction of an objects final position from it's initial position.

Front 3

Vector

Back 3

quantity that is specified by both it's size and direction.

Front 4

Speed

Back 4

distance an object travels per unit of time

Front 5

Instantaneous Speed

Back 5

speed at a single instant of time

Front 6

Average Speed

Back 6

total distance traveled/total travel time
v^- =d/t

Front 7

velocity

Back 7

speed on an object and direction of motion

Front 8

acceleration

Back 8

change in velocity divided by the time it took to occur
a= vf-vi/tf-ti

Front 9

force

Back 9

push or pull that an object exerts on another.

Front 10

Net Force

Back 10

when two or more forces act on an object at the same time.

Front 11

Balanced Forces

Back 11

forces on an object that are equal in size and opp in direction.

Front 12

Friction

Back 12

force that opposes the sliding the sliding motion of two surfaces that are in contact.

Front 13

static friction

Back 13

force that prevents two surfaces from sliding past each other.

Front 14

Sliding friction

Back 14

force that acts on the opposite direction to the motion of a surface sliding on another surface.

Front 15

Air Resistance

Back 15

opposes the movement of an object that moves through the air.

Front 16

Terminal velocity

Back 16

highest velocity the falling obj will reach.

Front 17

Isaac Newton

Back 17

Published a set of three called the Newton's Laws of Motion.

Front 18

1ST Law of Motion

Back 18

states that if the net force of an obj is 0, the object stays at rest, if the obj is moving, it continues moving at a constant speed.

Front 19

inertia

Back 19

tendency of an onbject to resist a change in it's motion.

Front 20

2nd law of motion

Back 20

states that the acceleration of an obj is in the same direction as the net force on the obj.

Front 21

you can calculate net force with the second law by:

Back 21

a=fnet/mass

Front 22

gravity

Back 22

attractive forces between two objs that depends on the mass and distance between them.

Front 23

gravitational force equation:

Back 23

f=mg

Front 24

Weight + equation

Back 24

gravitational force exerted on an obj.
W=mg

Front 25

centripetal acceleration:

Back 25

acceleration towards the center or a curved or circular path.

Front 26

centripetal force

Back 26

net force exerted towards the center of a curved path

Front 27

3rd law of motion

Back 27

for every action force there is an equal and opposite reaction.

Front 28

momentum + equation

Back 28

product of its mass and velocity
p=mv

Front 29

law of conservation of momentum

Back 29

if objs exert forces only on each other, their total momentum is conserved.

Front 30

collision

Back 30

momentum is transferred from one obj to another.
