Vectors&Projectiles Review

Front

What happens to the horizontal velocity (Vx) of an object when it is dropped from a moving airplane, neglecting air resistance?

Back

The horizontal velocity (Vx) remains constant and is the same as that of the airplane.

Front

What is the symbol for horizontal displacement in projectile motion?

Back

dx

Front

What is the symbol for horizontal velocity in projectile motion?

Front

In projectile motion, what remains constant if we ignore air resistance?

Back

Horizontal velocity (Vx) remains constant.

Front

What is the term for the sum of multiple vectors?

Back

Resultant Vector

Front

Define a vector in physics.

Back

A vector is a quantity that has both magnitude and direction.

Front

What is a scalar quantity? Give an example.

Back

A scalar quantity has only magnitude and no direction. Example: temperature.

Front

Explain the concept of projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to gravitational acceleration, following a curved path.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, affecting its velocity and trajectory.

Front

How do you calculate the resultant vector of two vectors?

Back

The resultant vector can be calculated using the Pythagorean theorem if the vectors are perpendicular.
