nope , just stating a fact.

so N*seconds = N because seconds are built into the units of force Newtons N

else

f/s^2 = ma




80N * 1 second = 80N



80N * 50 seconds = 4000N

for each 100kg mass that is accelerated at an acceleration rate of .8m/s/s for a time period of 50 seconds

the total force that is applied / consumed / expended is 4000N

because there is already 1 second^2 in each newton.

so the force applied wouldnt be written as
4000Ns it would be written as 4000N thats why they put the 1 second^2 in the definition of a newton.

1 N = 1 kg·m/s2

constant force means you constantly apply the force , its not a 1 time force applied for 1 second.

so you multiply the force applied times the time the force is applied.

kg =
meter =
second=

1 newton = 1 / per

if I apply a push of 1 over a distance of 1 in 1 per

I have applied 1kg-m/s^2 force for a distance of 1 meter for a time of 1 second per second

1kg-m/s^2 = 1N

if I apply a push of 80 over a distance of 1 in 1 per

I have applied 80kg-m/s^2 force for a distance of 1 meter for a time of 1 second per second

80kg-m/s^2 = 80N

if I apply a push of 4000 over a distance of 1 in 1 per

I have applied 4000kg-m/s^2 force for a distance of 1 meter for a time of 1 second per second

4000kg-m/s^2 = 4000N


if I apply a push of 80 over a distance of 1000 in 50 per 50

I have applied 4000kg-1000 meters/50 seconds per 50 seconds force for a distance of 1000 meters for a time of 50 seconds per 50 seconds

1kg-1m/1s^2 = 1N
so
4000kg-1000m/50s^2 = 4000N

dick =
jane =
force units = 80kg-m/s^2 = 80N =

dick can push jane with a force of 80N

jane has a mass of 100kg

dick can accelerate jane to an acceleration rate of .8 m/s/s
in 1 second.

see dick run

dick must use up 1 force unit to push jane every second that he pushes jane.

how many force units must dick have to push jane for 50 seconds?

dick uses up alot of force units pushing jane for 50 seconds.

can you count the number of force units that dick uses up pushing jane in 50 seconds?







did dick use up 50 force units pushing jane for 50 seconds?

yes dick used up 50 force units pushing jane for 50 seconds.

since 1 force unit = 80N what is the total number of N that dick used up pushing jane?

80N * 50 force units = 4000N

if 1 force unit gets used up each second can you find the total number of N that dick used up by using seconds.

80N * 50 seconds = 4000N

Ok children I know that your brains must be tired by now
so put your books under your desk and lay your heads on your desk and take a nap.

those of you who are already asleep just remain sleeping.
