# Force Formula

Force Formula

Force is the mass of an object, multiplied by its acceleration. The unit of force is . This is called a Newton, with the symbol N. Force has a magnitude and a direction.

*force = mass x acceleration*

*F = ma*

*F = force*

*m = mass*

*a = acceleration*

Force Formula Questions:

1) A *0.15 kg* coconut falls out of its tree. The acceleration due to gravity is *9.80 m/s ^{2}*, down. What is the force acting on the coconut due to gravity?

Answer: The force can be found using the equation:

*F = ma*

*F = (0.15 kg)(9.80 m/s ^{2})*

*F = 1.47*

*Solve: F = ?.?? N*

The force due to gravity acting on the coconut is 1.47 N, down.

2) A man pushes a *50.0 kg* block of ice across a frozen pond. He applies a force of 25.0 N, pushing the block away from him. What is the acceleration of the block?

Answer: To find the acceleration, rearrange the equation:

*Solve: a = ?.?? m/s ^{2}*

The block is accelerating 0.?? m/s^{2}, directed away from the man.
