... Ben Tooclose is being chased through the woods by a bull moose which he was attempting to photograph. The enormous mass of the bull moose is extremely intimidating. Yet, if Ben makes a zigzag pattern through the woods, he will be able to use the large mass of the moose to his own advantage. Explain ...

Newton`s 2nd Law
... Now push with 150 N; friction is still 100 N. Does the crate accelerate? Yes, because net force is now 50 Newtons. A friend helps push with an additional 150 N. By how much does acceleration increase? Net force is now 150+150-100= 200 N. This is FOUR times larger so acceleration increases by a facto ...

... The acceleration of an object is in the same direction as the net force. The formula can be arranged to show how much force must be applied to an object to get it to accelerate at a certain rate. Net force = Mass × Acceleration or F = ma For example, you apply a net force to a ball when you throw it ...
