Question

What is Newton's second law of motion?

What is the equation of acceleration when dealing with forces and mass?
What is the unit you use when dealing with Force?
BLANK (amount/unit of force) is the force necessary to change the speed of a BLANK (amount/unit of mass) by BLANK (amount/unit of length&time) every second.
If an object has a mass of 10 kg, what is the weight in N?
BLANK amount/unit of mass) is the force exerted by gravity on a mass of (amount) kg.

Answer 1

Newton's second law of motion states that the acceleration of a system is directly proportional to the net external force acting on it and inversely proportional to its mass. The unit used to measure force is the newton (N). If an object has a mass of 10 kg, its weight can be calculated using the formula weight = mass x acceleration due to gravity.

Step-by-step explanation:

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. This can be expressed mathematically as Fnet = ma. The unit used when measuring force is the newton (N), which is the force needed to accelerate a 1-kg system at the rate of 1 m/s².

If an object has a mass of 10 kg, its weight can be calculated using the formula weight = mass x acceleration due to gravity. The acceleration due to gravity on Earth is approximately 9.8 m/s², so the weight of the object would be 10 kg x 9.8 m/s² = 98 N.
