This MayeleCalc guide explains the concept in plain language so you can use the related calculator with better context and confidence. Work through each section, review the practical example, and check the common mistakes before applying the result.
Force changes motion
Newton’s second law states that net force equals mass multiplied by acceleration. For the same mass, larger net force produces larger acceleration.
Net force includes direction
Multiple forces may act at once. Forces in opposite directions subtract, so net force—not simply one applied force—determines acceleration.
Mass is not weight
Mass describes the amount of matter and is measured in kilograms. Weight is a force caused by gravity and is measured in newtons.
Keep SI units consistent
Using kilograms, metres per second squared, and newtons keeps the equation consistent. Convert other units before substituting values.
Practical example
See the idea in action
If a vehicle travels 120 kilometres in 2 hours, its average speed is 120 ÷ 2 = 60 km/h. This represents the full journey, including any slower sections or stops included in the time.
Common mistakes to avoid
- ×Mixing metres with kilometres or seconds with hours
- ×Confusing average speed with speed at one instant
- ×Leaving out direction when the question asks for velocity
Key takeaways
- ✓Convert units before inserting values
- ✓Rearrange the equation to match the unknown
- ✓Check whether the question asks for an average or instantaneous value
