Exploring Force and Pressure

Force is an interaction that causes an object to change its velocity.

Force is the distance an object travels over time.

Force is a type of energy that can be stored.

Force is the mass of an object multiplied by its acceleration.

Frictional forces and gravitational forces

Balanced forces and unbalanced forces

Contact forces and non-contact forces

Magnetic forces and electrical forces

Gravitational force is the attraction between two masses.

Gravitational force is the force that keeps objects in a straight line.

Gravitational force only acts on objects in motion.

Gravitational force is a repulsive force between two masses.

Contact forces involve direct interaction; non-contact forces act at a distance.

Contact forces can only be felt through touch; non-contact forces cannot be felt at all.

Contact forces are always stronger than non-contact forces; non-contact forces are weak.

Contact forces are only found in liquids; non-contact forces are only found in solids.

Pressure is the temperature of a fluid at rest.

Pressure is the volume of a fluid divided by its mass.

Pressure is the force per unit area exerted by a fluid.

Pressure is the weight of a fluid in motion.

P = F/A or P = P0 + ρgh

P = mv^2

P = 2πr

P = mgh

Atmospheres (atm)

Millimeters of mercury (mmHg)

Pascals (Pa)

Newtons per square meter (N/m²)

Pressure decreases with depth in a fluid.

Pressure fluctuates randomly with depth in a fluid.

Pressure increases with depth in a fluid.

Pressure remains constant regardless of depth in a fluid.

Increased pressure can cause deformation, affect buoyancy, and change volume.

Pressure only affects the surface of the object.

Increased pressure always increases buoyancy.

Pressure has no effect on submerged objects.

Atmospheric pressure is irrelevant to breathing.

Atmospheric pressure affects our breathing, health, and daily activities.

It has no impact on human health or activities.

Atmospheric pressure only affects weather patterns.
