Newton's+Three+Laws

Newtons Laws of Motion 1.Newton's first law states that an object moves with a velocity thats constant in magnitude and direction, unless acted on by a nonzero net force. 2.Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula is F=ma 3. Newton's third law states that for every action there is a equal and opposite reaction.

This is a example of Newtons first law of motion. 1Question:If an object's velocity isn't changing in either magnitude and direction, then what does the acceleration and the net force acting on it equals. This is a example of Newtons second law of motion. 2Question:The boat has a mass of 3.5*10^2kg, and has a engine that produces a net horizontal force of 7.70*10^2 N, after accounting for forces of resistance.Find the acceleration of the boat. This is a example of Newtons third law of motion. 3Question:The skateboard puts force on the ground, so what does the ground do to the skateboard.

Answers: Answer1: The acceleration and the net force equals zero. Answer2:F=ma a= F/m a=7.70*10^2 N/ 3.5*10^2 kg a= 2.2 m/s^2 Answer3:The ground also puts force on the skateboard. Links to other websites about Newtons Laws: [] [] []
