Newton's second law of motion/law of acceleration

Question 1

What does Newton’s second law of motion/law of acceleration state?

Answer 1

“If a net force is acting on an object, it will accelerate in the direction of the net force. The magnitude of the acceleration is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object.”

Question 2

(Review from previous lesson)

What is the fomula and unit of measurment for finding weight?

Answer 2

W = mg

unit of measurement:
kg m/s^2
or
N (Newtons)

weight = mass of object x acceleration of gravity

Question 3

Fomula and unit of measurment for gravitational acceleration

Answer 3

g = W/m

unit of measurement:
m/s^2

gravitational acceleration = weight / mass of object

Question 4

fomula and unit of mass?

Answer 4

m = w/g

unit of measurement:
Kg

mass = weight / gravitational acceleration

Question 5

refers to the change in speed or direction of the movement or change in velocity due to the exerted force.

Answer 5

Acceleration

Question 6

fomula for force/net force

Answer 6

F = ma

unit: N (Newtons)

Force = mass x acceleration

Question 7

fomula of acceleration

Answer 7

a = f / m
or
a = (vf - vi) / t

unit: m/s^2

acceleration = final velocity - initial velocity / time
