Newton's Second Law Calculator: F = ma Solver

Your details

Choose which quantity you want to calculate. The other two become inputs.
The amount of matter in the object. More mass means more force is needed to accelerate it.
The rate of change of velocity. On Earth, gravity accelerates objects at about 9.8 m/s^2.
Force (F)

Net force acting on the object

Acceleration in m/s²9.8
Acceleration in g0.9993
Force unitN
Mass unitkg
Acceleration unitm/s2
Force (N)98

Net force is 98.000 N

  • A 10.00 kg object accelerating at 9.800 m/s² experiences a net force of 98.000 N.
  • This acceleration (0.999 g) is less than the pull of Earth's gravity (1 g = 9.80665 m/s²).
  • Newton's Second Law tells us that doubling the mass at the same force would halve the acceleration, and doubling the force at the same mass would double the acceleration.

Next stepTo find how far the object travels under this force, use a kinematics calculator with initial velocity and time.
