applying newtons laws to angular motion

Question 1

define angular motion

Answer 1

movement around a fixed point or axis

an off centre force is a rotational force (eccentric force/torque)

Question 2

what is newtons first law

Answer 2

an objects resistance to change its state of motion (inertia)

Question 3

what is newtons second law

Answer 3

the acceleration of an object is directly proportional to the force applied (acceleration)

Question 4

what is newtons third law

Answer 4

every action has an equal and opposite reaction

Question 5

what is newtons first law of angular motion

Answer 5

an objects resistance to change its state of motion whilst rotating

Question 6

what is newtons second law of angular motion

Answer 6

the rate of change of anguar momentum is directly proportional to the rotational force acting on it

Question 7

what is newtons third law of angular motion

Answer 7

for every rotational action there is an equal and opposite rotational reaction

Question 8

define angular displacement

Answer 8

the smallest change in an angle between the start and finish point (measured in radians)

Question 9

how many degrees in 1 radian

Answer 9

57.3 degrees

Question 10

define angular velocity

Answer 10

the rotational speed of an object around the axis it is rotating

Question 11

define angular acceleration

Answer 11

the rate of change of angular velocity

Question 12

how do you calculate angular velocity (rad/s)

Answer 12

angular displacement(rad)/time taken(s)

Question 13

how do you calculate angular acceleration (rad/s^2)

Answer 13

change in angular velocity(rad/s)/time taken(s)
