Fall 2024 Final Exam Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line on a distance-time graph, indicating that the object is moving at a steady pace.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force of attraction between two masses, described by Newton's law of universal gravitation.

Front

How do you calculate gravitational force between two objects?

Back

The gravitational force (F) can be calculated using the formula: F = G * (m1 * m2) / r², where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the difference between power and work?

Back

Power is the rate at which work is done, calculated as work done per unit time (P = W/t). Work is the energy transferred when a force is applied over a distance.

Front

What is the formula for work?

Back

Work (W) is calculated using the formula: W = force * distance * cos(θ), where θ is the angle between the force and the direction of motion.

Front

What does the area under a velocity-time graph represent?

Back

The area under a velocity-time graph represents the displacement of the object during that time interval.

Front

How do you calculate displacement from a velocity-time graph?

Back

Displacement can be calculated by finding the area under the curve of a velocity-time graph.

Front

What is the unit of power?

Back

The unit of power is the Watt (W), which is equivalent to one Joule per second (J/s).
