Physics Final Review

Front

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What does it mean when an object is decelerating?

Back

Decelerating means that the object is slowing down, which indicates a negative acceleration.

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as mgy, where m is mass, g is the acceleration due to gravity, and y is height.

What happens to the horizontal component of a projectile's acceleration in the absence of air resistance?

Back

The horizontal component of a projectile's acceleration remains zero.

Front

How does the gravitational force between two objects change if the distance between them is tripled?

Back

The gravitational force is cut in one-ninth.

What is the relationship between force, mass, and acceleration according to Newton's second law?

Back

The relationship is given by the formula F = ma, where F is force, m is mass, and a is acceleration.

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.
