The coefficient of kinetic friction between block and incline changes with velocity.

The incline angle remains constant throughout the motion.

The mass of the block is doubled while keeping all other factors constant.

There is no air resistance acting on the block as it slides down the incline.

The skater stays inside due to throwing the backpack gently enough to not induce any motion.

The skater moves in the same direction as the backpack due to increased momentum transfer to herself by throwing the object.

The skater experiences sudden forward acceleration due to impulsive force transferred from the backpack to propel her.

The skater will move in the opposite direction to the backpack due to conservation of momentum and lack of frictional forces to counteract her motion.

Air resistance has a greater effect on smaller amplitude swings.

The period of oscillation can be easily calculated using simple harmonic motion formulas.

The tension in the pendulum string remains constant throughout motion.

The restoring force is nonlinear resulting in angular accelerations that vary throughout motion.
