Honors Physics 1st Sem Final Exam

Front

What is velocity?

Back

Speed in a specific direction.

Front

What happens at point e in a parachutist's journey?

Back

He has reached terminal velocity with his parachute.

Front

If two objects are released at the same time, one dropped vertically and one launched horizontally, which hits the ground first?

Back

Both hit the ground at the same time.

Front

What is a change in velocity over time called?

Back

Acceleration.

Front

Calculate the velocity of a plane that traveled 3000 miles west in 5 hours.

Back

600 mph west.

Front

What is acceleration?

Back

The rate of change of velocity over time.

Front

Define 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 the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes direction.

Front

What is projectile motion?

Back

The motion of an object thrown into the air, subject to the acceleration of gravity.

Front

What factors affect the trajectory of a projectile?

Back

Initial velocity, angle of launch, and acceleration due to gravity.
