IPC '24 Fall Semester Review

Front

What opposes gravity?

Back

Air resistance is the force that opposes the motion of an object through the air, acting against gravity.

Front

What is speed?

Back

Speed is defined as the total distance traveled (in meters) divided by the time (in seconds) taken to travel that distance.

Front

How is thermal energy transferred from the sun to the Earth?

Back

Thermal energy is transferred from the sun to the Earth by radiation, which is the transfer of energy through electromagnetic waves.

Front

What is momentum?

Back

Momentum is the resistance of an object to change direction or stop moving, calculated as the product of an object's mass and its velocity.

Front

Which letter represents a proton?

Back

A represents a proton in atomic models.

Front

What is the formula for calculating speed?

Back

Speed = Total Distance / Time Taken.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object, pulling them towards each other.

Front

What is the role of air resistance in free fall?

Back

Air resistance acts against the force of gravity, slowing down the acceleration of a falling object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.
