# How can force affect the motion of an object?

If a net force acts on an object, from Newton's second law, it experiences an acceleration in the direction of the net force.

According to Newton's second law,

Acceleration changes an object's velocity; depending on the circumstances, it may change an object's speed, direction of motion, or both.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A block weighing #6 kg# is on a plane with an incline of #(5pi)/6# and friction coefficient of #4/5#. How much force, if any, is necessary to keep the block from sliding down?
- If a #2 kg# object moving at #5 m/s# slows down to a halt after moving #3 m#, what is the friction coefficient of the surface that the object was moving over?
- An object with a mass of #7 kg# is hanging from a spring with a constant of #2 (kg)/s^2#. If the spring is stretched by # 3 m#, what is the net force on the object?
- An object with a mass of # 5 kg# is lying still on a surface and is compressing a horizontal spring by #2 m#. If the spring's constant is # 6 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
- An object with a mass of #4 kg# is lying still on a surface and is compressing a horizontal spring by #7/8 m#. If the spring's constant is #16 (kg)/s^2#, what is the minimum value of the surface's coefficient of static friction?
