A conversion of kinetic energy into potential energy.

The total kinetic energy before and after the collision is conserved.

A decrease in kinetic energy due to internal friction.

An increase in kinetic energy due to external work.

The angle at which bullet strikes the block.

The bullet’s initial momentum.

The gravitational pull on the bullet-block system.

The block's material properties.

Using colored smoke trails to trace the path of motion and visually distinguish instances where external work is being applied.

Substituting standard weights with hooked weights of differing materials, despite similar masses, to ensure a distinction due to the merely weight type.

Increasing the loudness of sounds produced by contacts between objects to ascertain whether sound level correlates with the loss of kinetic energy.

Implementing a device that continuously applies force in a direction perpendicular to the initial velocity vector of the moving object throughout the demonstration.

It increases.

It decreases.

It remains the same.

It turns into potential energy entirely.

Electrons ejected from metals would have less kinetic energy since h inversely affects electron velocity.

Fewer electrons would be ejected as energy per photon increases and fewer photons have sufficient energy.

There will be no change since Planck’s constant does not influence photoelectric effects on metals.

Metals' work function values decrease, leading to an increased number of ejected electrons at lower frequencies.

The use of velcro on one cart that sticks only when both carts are at specific velocities before collision.

Equipping one cart with a mass that changes over time through mechanical means.

Modifying wheel diameters on each cart without changing their masses.

Applying different colored lights on each cart for visual tracking during collisions.

West, opposing original momenta vectors leading to recoil effect.

North, due to dominance in northern directional inertia.

East, since eastward motion conserves more initial velocity component.

Northeast, following the principle of vector addition for momenta.

Equal final velocities arise regardless differing masses due interaction symmetry.

Smaller mass particle maintains initial velocity larger stops altogether.

Larger mass particle maintains initial velocity while smaller one reverses direction.

Differing masses result unequal final velocities determined via conservation laws.
