Physics Semester Exam Review

Front

What is the curved path that an object follows when thrown or launched near the surface of the Earth?

Back

Projectile Motion: The motion of an object that is thrown or projected into the air, subject to the force of gravity.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance ÷ Total Time

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the formula for acceleration?

Back

Acceleration = (V2 - V1) ÷ T

Front

What is terminal velocity?

Back

The constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

What is free fall?

Back

The motion of an object falling solely under the influence of gravity, with no air resistance.

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 the unit of force in the International System of Units (SI)?

Back

Newton (N): The force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What is kinetic energy?

Back

The energy that an object possesses due to its motion, calculated as KE = 1/2 mv².
