Example of
Acceleraton: How to calculate Speed, Force, and Acceleration By: Jade Cantrell Another example of calculating force: Case 2: What would be the acceleration of an object with a mass of 20 kg when hit with a force of 100 N?
F = 100 N, m = 20 kg
Step 1: Substitute the values in the below Acceleration formula:
The End
^.^ The equation for is
force = mass x acceleration or f = ma
The standard unit for mass is kg.
The standard unit for acceleration is m/s2.
The standard unit for force is newton (N). A newton is a derived standard unit. This means that the SI unit of newton is composed of two or more standard units. 1N = 1 kg x 1m/s2. Calculating Speed: A car starts from rest and accelerates at 2 m/s/s for 5 seconds. How fast will it be going?


The statement "car starts from rest" means that the car's starting velocity is 0 m/s. An acceleration of 2 m/s/s means that the car's velocity changes by 2 m/s each second. If the car's velocity starts at 0 m/s and changes by 2 m/s in the first second, it will be going 2 m/s after 1 second has elapsed. During the second second (?!), its velocity increases by 2 m/s - from 2 m/s to 4 m/s. Its velocity will be 6 m/s after 3 seconds, 8 m/s after 4 seconds, and 10 m/s after 5 seconds.

Alternatively, there is a more-algebraic approach if you prefer. If then , so . If the velocity starts at 0 m/s and changes by 10 m/s, it ends at 10 m/s. How to calculate Acceleration: Calculating Force Examples of Calculating Force: Case 1: What force is required to accelerate an object having a mass of 4 kg at 7 m/s2?
m = 4 kg, a = 7 m/s2
Step 1: Substitute the values in the below force formula:
Speed is measured in m/s (meters per second)
You can calculate speed using the following formula :
Speed = Distance/Time
Example: distance=100 meters=20s
s= 5m/s
the units for speed equal up to m/s units always.
so then your speed is 5 m/s a = F/m, where F is the net force applied to a mass, m. Sources:
