Physics: Projectile Motion

Front

What is a vector?

Back

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

Front

True or False: The orientation of a vector shows the direction.

Back

True

Front

Does the vertical component of a projectile's velocity change in the absence of air friction?

Back

No, it does not change.

Front

What is the resultant of two 6-unit vectors at right angles to each other?

Back

The resultant is approximately 8 units.

Front

Which of the following is NOT a projectile? A cannonball thrown straight up, a cannonball rolling down a slope, a cannonball rolling off a table, a cannonball thrown in the air.

Back

A cannonball rolling down a slope.

Front

What does 'magnitude' refer to in physics?

Back

Magnitude refers to the size or quantity of a vector.

Front

What is 'direction' in the context of vectors?

Back

Direction indicates where the vector is pointing.

Front

What happens to a projectile's horizontal velocity in the absence of air resistance?

Back

The horizontal velocity remains constant.

Front

What is the formula for calculating the resultant of two perpendicular vectors?

Back

Resultant = √(A² + B²) where A and B are the magnitudes of the vectors.

Front

What is an example of a projectile?

Back

A ball thrown into the air.
