Newton's Laws of Motion

Tangential acceleration increases

There is no tangential acceleration at any point

It decreases

Tangential acceleration remains constant

Conservation of angular momentum

Conservation of linear momentum

Decrease in gravitational potential energy leading to an increase in speed

Increase in kinetic energy due to work done by a force

The period calculation yields slightly lower values than actual since some mass extends beyond pivot contributing less effectively.

Calculated periods end up higher due to overestimation of gravitational torque influence throughout pendulum swing arc.

Period outcomes become imprecise regardless given inherent complexity governing physical pendula motions versus simplified models.

Periods remain largely unaffected provided length measurements accurately represent distance from pivot point center-of-mass.

Stopping distance decreases as smooth ice converts less kinetic energy into heat.

The stopping distance would be greater due to reduced frictional force opposing its motion.

The stopping distance would not change because mass and initial speed are constant.

The stopping distance would be shorter as there is less kinetic energy due to smoother ice.

Spin objects with identical mass but different shapes on low-friction bearings and measure any differences in rotational speeds achieved.

Drop two identically sized spheres—one hollow and one solid—from height onto a rotating platform, observing bounce patterns post-impact for deviations caused by rotation-induced forces

Measure how long it takes for objects with varying densities but fixed outer dimensions when spun up until they reach certain RPMs using external torque applied evenly across their surfaces

Compare accelerations on small masses placed at equal radii but different angular positions inside a spinning disk enclosed within an evacuated chamber to eliminate air resistance effects.

Object must not be moving

Net force on the object must be zero only

Net torque about any axis must be zero

Angular velocity must be increasing

It stays the same.

Start over and repeat the question.

It decreases.

It increases.

It will slowly start moving due to internal forces.

It will move with a constant velocity.

It will accelerate randomly over time.

It will remain at rest.
