How can you use Newton's second law to find force-?

Answer 1

To find the force:

Mass x Acceleration

Example:

F=m*a

F=55 kg * 2.0 m/s^2

F= 110 kg*m/s^2

F=110 N

(Because "kg" times "m/s^2" is (N))

To find The Acceleration:

Net Force/ Mass

Answer 2

To find the force:

Mass x Acceleration

Example:

F=m*a

F=55 kg * 2.0 m/s^2

F= 110 kg*m/s^2

F=110 N

(Because "kg" times "m/s^2" is (N))

To find The Acceleration:

Net Force/ Mass

Answer 3

Newton's Second Law is usually expressed as:F = ma (net force = mass x acceleration)

Since "F" (the net force) is already alone on the left, you need no further algebra to solve for "F". Just replace the mass and the acceleration, and multiply them to find the force.

Note: You can find any of the three variables F, m, a, from the other two. If you don't know two of them, you need additional information, or measurements, before you can apply Newton's Second Law.

Answer 6

The formula from Newton's 2nd law is: Force = (mass) x (acceleration). Note that this is the Net force acting on an object results in an acceleration. Consider dropping a smooth rock, with little air resistance. Most of the force on it, is due to gravity, so it accelerates near the earths gravitational acceleration. Now consider a skydiver. After falling awhile, it reaches what we call terminal velocity, which means the force from the air pushing against the direction of motion is equal to the force of gravity pulling down. The person stops accelerating and moves at a constant velocity (actually all objects would have a terminal velocity - some could be much greater than others, though).

In the case of the person at terminal velocity, the force up is equal to the person's weight. Net force is zero.

Answer 7

Use circular motion equations to determine any unknown information.
