Newtonian Mechanics and Forces

Speed is defined as the distance traveled per unit of time. It measures how quickly an object changes its position.

Motion is defined as a change in an object's position relative to a reference point over time.

Position describes the location of an object relative to a reference point.

Since pressure is force divided by area (P = F/A), increasing the area over which the same force is applied will decrease the pressure.

Pressure is defined as the force applied perpendicular to the surface of an object per unit area. Therefore, the formula is force divided by area.

Pressure is the physical quantity that measures the intensity of a force distributed over a specific area. Buoyancy, inertia, and fluidity represent different physical concepts.

Centripetal force is the net force that acts on an object to keep it moving along a curved path. In a loop-the-loop, this force is provided by the track.

When you accelerate, your body experiences an inertial force in the opposite direction of the acceleration, which is what you feel as pressure or weight.

Weightlessness occurs when the normal force is zero, meaning gravity and acceleration are balanced in a way that the object is in free fall.

Newton's 1st Law, also known as the Law of Inertia, states that an object in motion stays in motion unless acted upon by an external force.

Inertia is the tendency of an object to resist changes in its state of motion. Once a coaster has velocity, inertia keeps it moving forward.

Gravity is the force that pulls the coaster car down the track, converting potential energy into kinetic energy.

Kinetic energy is highest when the coaster is moving at its maximum speed, which typically occurs at the bottom of the first major drop.

Roller coasters operate primarily by using gravity to provide energy and inertia to maintain motion through turns and loops.
