If you see an object rotating, is there necessarily a net torque acting on it?

There need not necessarily be net torque acting on a rotating object.

<h3>What is angular acceleration?</h3>
  • Angular acceleration is the term used to describe the temporal pace at which angular velocity varies. Radians per second is the accepted unit of measurement. Consequently, = d d t. Angular acceleration is also known as rotational acceleration.
  • Angular acceleration can be calculated by dividing the angular velocity by the acceleration duration. (t). Use pi instead, or the drive speed (n) divided by the acceleration time (t) multiplied by 30. The usual SI unit for the rotational acceleration that results from this equation is radians per second squared (Rad/sec2).

Is there always a net torque acting on an object when you perceive it rotating?

  • Torque, force, and angular acceleration are the ideas applied to this problem's solution.
  • Use the notion of force to first determine whether there is net torque operating on a rotating body.
  • Then, using the idea of angular acceleration, determine whether there is net torque operating on a rotating body.
  • Torque is the measure of the amount of force that causes a body to accelerate in one direction. It is often referred to as the rotational force of a body.

Step: 1

  • The torque of a spinning body can be zero if an object's total amount of forces acting on it is zero or if the object is in rotational equilibrium.
  • A vector quantity is a torque. There won't be any net torque acting on the body if the forces causing the rotation are equal and opposing.
  • Using the idea of angular acceleration, determine whether there is net torque operating on a rotating body.
  • The body's angular acceleration will be 0 if it is rotating with constant angular speed. The net torque is 0 for a body with 0 angular acceleration.

There need not necessarily be net torque acting on a rotating object.

An astronaut's pack weighs 17.5 N when she is on earth, but only 3.24 N when she is on the surface of an asteroid. What is the a
Nimfa-mama [501]

Answer:

a= 1.81 m/s²

Explanation:

Ratio of the weights on both surfaces can be calculated as,

\frac{W_{a} }{W_{E} }=\frac{ma}{mg}

Here;

   Wa is the weight on the asteroid,       W_{E} is weight on earth,

         m is mass of pack,          a is acceleration due to an asteroid and

         g is acceleration due to gravity.

         Rearrange above equation for a,

           a=g (\frac{Wa}{W_{E} })

Substitute 3.24 N for Wa,       17.5 N for  W_{E},

          9.81 m/s² for g in the above equation,

          a= 9.81(\frac{3.24}{17.5})

          a= 1.81 m/s²

A rocket traveling at 80 m/s is accelerated uniformly to 152 m/s over a 18 s interval. What is its displacement during this time
IgorLugansk [536]

Recall that with constant acceleration,

x_f-x_i=\dfrac{v_i+v_f}2t

where x_f-x_i is the rocket's displacment, v_i is its initial velocity, v_f its final velocity, and t is time. So

x_f-x_i=\dfrac{80\frac{\mathrm m}{\mathrm s}+152\,\frac{\mathrm m}{\mathrm s}}2(18\,\mathrm s)=2088\,\mathrm m

or just 2100 m if taking significant digits into account.

the average velocity of a duck is zero as it goes from t=0 to t=120 s. describe the displacement of the duck for that interval
podryga [215]

Answer:

The displacement, s= 0 m

Explanation:

Given data,

The average velocity of the duck, v = 0 m/s

The time interval of the velocity, t₁ = 0 and t₂ = 120 s,

                                       ∴                 Δt =  t₂ - t₁

                                                                = 120 s

The displacement of the duck is given by the formula,

                                         s = v x Δt

                                            = 0 m/s x 120 s

                                            = 0 m

Hence, the displacement of the duck is, s = 0 m

Which has greater force fly hitting windshield of rapidly moving car or the force of windshield hitting fly? Explain
Goshia [24]
The force applied on the fly and the windshield are equal based on Newton's Law of Action and Reaction. the difference between them is that the fly's body does not have enough mechanical strength to withstand the force but the windshield does.
