FAQ: Which Will Have The Greater Acceleration Rolling Down An Incline A Bowling Ball Or A Volleyball?

Which will have the greater acceleration?

If the same force acts on two objects, the object with less mass will have the greater acceleration. For instance, if you push a soccer ball and a bowling ball with equal force, the soccer ball will have a greater acceleration. If objects lose mass, they can gain acceleration if the force remains the same.

Is the net torque changed when a partner on a flat seesaw stands or hangs from her end rather than sitting?

Is the net torque changed when a partner on a seesaw stands or hangs from her end instad of sitting. The net torque stays the same. The lever arm will stay the same whether a person stands, sits or hangs from the end.

How much more friction is required for twice the speed?

How much more friction is required for twice the speed? If speed is increased by twice the original speed, the friction will need to be four times as much.

What does rotational inertia depend on?

• The rotational inertia (I) depends on the mass of the. object, its shape, and on how. the mass is distributed.

Which will have the greater acceleration rolling down an incline a hoop?

Which will have the greater acceleration rolling down an incline – a hoop or a solid disk? The solid hoop would have a greater acceleration.

Which car has the largest acceleration?

The Aspark Owl boasts the fastest acceleration of any car in the world, according to its Japanese manufacturers Aspark.

What does higher moment of inertia mean?

Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. When the body has an increased radius, i.e. during the initial and final phase of a dive, moment of inertia is large and angular velocity is small.

What is the net torque on the seesaw?

The net torque on the seesaw could be zero, but the seesaw could rotate with a contant angular speed. This would occur if one side of the seesaw were given an extra nudge while both sides were otherwise balanced.

Why did one sphere accelerate faster?

This is because the solid sphere will have more of its mass at a smaller distance from the axis of rotation. With its smaller “rotational mass”, the solid sphere is easier to rotate so the solid sphere will roll down a hill faster.

Is friction a centripetal force?

As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle.

What coefficient of friction do car tires need on a flat curve?

That is, we must have a coefficient of static friction of s = v2/g r to provide the friction force to allow a car, traveling at speed v, to make it around a flat curve of radius r. This is the maximum speed that a curve of radius r can be taken when the coefficient of static friction between tires and pavement is s.

How do you calculate force normal?

Normal Force Formula

  1. The normal force will be equivalent to the weight of the object only if the object is not accelerating i.e. decelerating.
  2. F_N = mg.
  3. F_N = mg + F sin;theta.
  4. F_N = mg – F sin;theta.
  5. F_N = mg cos;theta.
  6. Angle theta = 30°
  7. Sin 30° = frac{1}{2}
  8. F_N = mg + F sin;theta.

Is angular momentum always conserved?

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity —the total angular momentum of a closed system remains constant.

Does inertia depend on speed?

No, inertia does not depend on speed. Inertia solely depends on the mass. The more mass, the more inertia.

Does rotational inertia depend on radius?

Rotational inertia is a scalar, not a vector and is dependent upon the radius of rotation according to the formula rotational inertia = mass x radius^2.
