Law of acceleration

2. Law of Acceleration
- states that the acceleration of an
object is directly proportional to
the net force acting on it and is
inversely proportional to the
object’s mass.

3. Greater the mass = greater
amount of force needed to
accelerate

5. ∑Force= mass x acceleration
∑F=ma
acceleration= ∑Force / mass
A=∑F/m
mass= ∑Force/ acceleration
m=∑F/a

6. Equivalence:
∑Force= Newton (N)
Mass= weight
acceleration = 1m/s²
Weight= force due to gravity
w=mass x gravity 9.8m/s²

7. Problem# 1
A 1000kg truck is traveling at an
acceleration f 4.5000m/s², East.
Find the net force needed to
accelerate the truck.

8. Given: mass=1000kg
acceleration= 4.5000m/s²
Formula:
∑ F = ma
∑ F = 1000kg x 4.5000m/s²
∑ F = 4500kg.m/s² or Newton
East
