According to Newton's First Law
-
objects always seek a state of rest
-
If an object is in motion, it will always eventually slow down and come to rest.
-
once an object is in motion a force cannot change its velocity.
-
a force is necessary to maintain motion at constant velocity.
-
a force is necessary to cause an object to leave its state of rest are state of uniform motion

Which of the following is incorrect concerning Newton's First Law? I know that Newton's first law states an object at rest will remain at rest as long as the net force on the object is zero. I narrowed the questions down to three choices of the five: A) An object can not have a constant speed if the magnitude of net force is greater than zero. B) An object can not have a constant veloocity if the magnitude of net...

DQ Question 7 1 pts Suppose an object is moving in a straight line at 70 km/hr. According to Newton's first law of motion, the object will continue to move in a straight line forever if it is in space, but fall to the ground if it is on Earth. continue to move in the same way forever, no matter what happens. continue to move in the same way until it is acted upon by a force. eventually slow...

Large objects have inertia and tend to keep moving-Newton's first law. Life is very different for small microorganisms that swim through water. For them, drag forces are so large that they instantly stop, without coasting, if they cease their swimming motion. To swim at constant speed, they must exert a constant propulsion force by rotating corkscrew-like flagella or beating hair-like cilia. The quadratic model of drag given by the equation, D⃗ = (12CρAv2, direction opposite the motion), fails for very...
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...
