Physics Review Fall Semester 2022-2023

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is the formula for calculating the time of flight for an object thrown vertically?

Back

The time of flight (T) can be calculated using the formula T = 2 * (initial velocity / g), where g is the acceleration due to gravity (approximately 10 m/s²).

Front

What happens to the normal force as the angle of an incline increases?

Back

The normal force decreases as the angle of the incline increases.

Front

What is the principle of conservation of energy in physics?

Back

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

Front

How do you calculate the height of an object using its velocity and gravitational acceleration?

Back

Use the formula h = v² / (2g), where h is height, v is final velocity, and g is acceleration due to gravity.

Front

What is gravitational acceleration near the Earth's surface?

Back

Gravitational acceleration near the Earth's surface is approximately 10 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force exerted by gravity on that mass, measured in newtons (N).

Front

What is the formula for calculating acceleration?

Back

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

Front

What is a frictionless surface?

Back

A frictionless surface is an idealized surface where no frictional force opposes the motion of an object.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration and terminal velocity.
