Physics 111 Final Exam Game

Front

What is pressure difference and how is it calculated?

Back

Pressure difference is the difference in pressure between two points. It can be calculated using the formula: ΔP = ρgh, where ρ is the fluid density, g is the acceleration due to gravity, and h is the height difference.

Front

What is the formula for tension in a string when pulling an object?

Back

Tension (T) can be calculated using Newton's second law: T = m(a + g), where m is the mass of the object, a is the acceleration, and g is the acceleration due to gravity.

Front

How do you calculate the final speed of an object falling from a height?

Back

The final speed (v) can be calculated using the formula: v = √(2gh), where g is the acceleration due to gravity and h is the height from which the object falls.

Front

What is escape speed and how is it derived?

Back

Escape speed is the minimum speed needed for an object to break free from a celestial body's gravitational pull. It is derived from the formula: v = √(2GM/R), where G is the gravitational constant, M is the mass of the body, and R is its radius.

Front

What is gravitational potential energy and how is it calculated?

Back

Gravitational potential energy (U) is the energy an object possesses due to its position in a gravitational field. It is calculated using the formula: U = -GMm/r, where G is the gravitational constant, M is the mass of the body creating the field, m is the mass of the object, and r is the distance from the center of the mass.

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a key quantity in Newton's law of universal gravitation, representing the strength of the gravitational force between two masses.

Front

What is the relationship between mass, weight, and gravity?

Back

Weight (W) is the force exerted by gravity on an object and is calculated as W = mg, where m is the mass of the object and g is the acceleration due to gravity.

Front

How does fluid pressure change with depth?

Back

Fluid pressure increases with depth due to the weight of the fluid above. The relationship is linear and can be expressed as P = P0 + ρgh, where P0 is the pressure at the surface.

Front

What is the concept of net force and how is it calculated?

Back

Net force is the total force acting on an object, calculated by summing all individual forces acting on it, taking into account their directions.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
