Question

HELP!
2. If an object has a mass of 5 kg and falls with an acceleration of 1 m/s2 What is the force acting on the object? (1 point)
5 N
2.5 N
1 N
10 N

Answer 1

Newtons 2. law of motion.
"The acceleration a of a body is parallel and directly proportional to the net force F acting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body" - wiki
Or mathematical:
\[F=ma\]

Answer 2

What does f m and a stand for?

Answer 3

F= force
m = mass
a = acceleration

Answer 4

So the force is 5 N?

Answer 5

Exactly.

Answer 6

k thanks! :)

Answer 7

The unit for newton is also:
\[N=\frac{ kg*m }{ s^{2} }\]

Answer 8

No problem.
