Question

1. The following can be inferred from Newton’s second law of motion except:

a) The acceleration of an object is (summation of F)/ m i.e. effective force divided by the mass

b) If a net non-zero force acts on an object, it will cause an acceleration of that object

c) The rate of change of the velocity is directly proportional to force applied and takes place in the direction of the force

d) The acceleration of an object is always less than the acceleration due to gravity, g (9.81m/s^-2)

2. How would you expect the acceleration to change if we gradually increase the mass of both sides of the Atwood, keeping the difference in mass constant?

a)acceleration decreases b) acceleration increases c) accelerations remains constant d) acceleration increases steadily from zero

Answer 1

Answer: 1.d) The acceleration of an object is always less than the acceleration due to gravity, g (9.81m/s^-2)

2.a)acceleration decreases

Step-by-step explanation:

Newton's second law:

Newton's second law states that the acceleration of an object is defined by two variables which is the total force acting on the object and the mass of that object. The acceleration is directly proportional to the net force that is applied on an object and inversely proportional to the mass of that object.

When the force applied on an object is increased so does the acceleration of an object however if the mass increase the acceleration decreases.

This can be felt when you look at the truck which usually carry heavy loads they seem to drive slow due to the load hence their acceleration is decreased by the mass that these truck carry .
