Newton's Second Law

Question 1

acceleration of an object is equal to the net force acting on an object divided by the mass

Answer 1

Newton’s Second Law

Question 2

any motion in which an object is moving along a curved path

Answer 2

circular motion

Question 3

in circular motion, a force that acts perpendicular to the direction of motion, towards the center of the curve

Answer 3

centripetal force

Question 4

what is force measured in?

Answer 4

Newton’s

Question 5

what is mass measured in?

Answer 5

kilograms

Question 6

what is acceleration measured in?

Answer 6

m/s2

Question 7

Force, acceleration, and mass triangle

Answer 7

F = (m)(a)
a = F/m
m = F/a

Question 8

Answer 9

unbalanced

Question 10

when unbalanced forces start acting on an object at __________, the object begins to __________ in the direction of the _______ ___________

Answer 10

rest
move
net force

Question 11

what is another name for a change in velocity over time?

Answer 11

acceleration

Question 12

the direction of acceleration is the same as the direction of the ____ __________

Answer 12

net force

Question 13

what is one example of something effected by centripetal force?

Answer 13

planets or any types of satellites

Question 14

what will happen if force is applied in the direction of the object’s motion

Answer 14

the object will speed up

Question 15

what will happen if force is applied in a direction other than that of the object’s motion

Answer 15

the object will slow down and/or change direction

Question 16

how many grams are in a kilogram

Answer 16

1000

Question 17

acceleration has which proportion to mass?

Answer 17

inverse

Question 18

what is the relationship between mass and acceleration?

Answer 18

less mass means faster acceleration

Question 19

what is the relationship between force and acceleration?

Answer 19

more force applied means faster acceleration

Question 20

with unchanging force, increasing the mass of an object will cause what?

Answer 20

a decrease in acceleration

Question 21

if I were to suddenly cut a string that a spinning ball was attached to, what would happen to the ball?

Answer 21

the body would fly out in the tangential direction that it was pointing towards

Question 22

centripetal force pulls on a body moving in a ____________ motion

Answer 22

circular

Question 23

an object’s _____________ depends on the mass and force acting on it

Answer 23

acceleration
