Physics Final Final Review

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. All objects have inertia, whether they are at rest or in motion.

Front

What is the unit of speed?

Back

The appropriate unit for speed is meters per second (m/s).

Front

What is physics?

Back

Physics is the branch of science that studies the physical world, including energy, matter, and their interactions.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. For example, a rollercoaster at the top of a hill has high potential energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to friction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between speed and distance?

Back

Speed is defined as the distance traveled per unit of time, typically expressed as distance/time.

Front

What is the formula for calculating speed?

Back

The formula for calculating speed is: Speed = Distance / Time.

Front

What is the significance of the lowest point in a rollercoaster?

Back

The lowest point in a rollercoaster typically has the least potential energy and the most kinetic energy.

Front

What is uniform circular motion?

Back

Uniform circular motion refers to the motion of an object traveling at a constant speed in a circular path.
