Projectile Motion Quiz

What do you call objects following a trajectory path or in two dimensions?

• A. Projectile

• B. Height

• C. Trajectory

• D. Range

Answer explanation

Objects following a trajectory path or in two dimensions are called projectiles, making option A the correct choice.

At what angle can you achieve longest range?

• A. 25 degrees

• B. 30 degrees

• C. 45 degrees

• D. 60 degrees

Answer explanation

The longest range is achieved at 45 degrees due to the optimal balance between horizontal and vertical components of the projectile motion.

Angles 30 and 60 are said to be complementary. What does this mean?

• A. Their sum is 180 degrees

• B. Their sum is 90 degrees

• C. They have the same range

• D. They have the same height

Answer explanation

Angles 30 and 60 are complementary, which means their sum is 90 degrees. Therefore, option B is the correct choice.

What is the relationship between angle of projection and height of the trajectory?

• A. Direct

• B. Indirect

• C. Inverse

• D. Joint

Answer explanation

The relationship between angle of projection and height of the trajectory is direct, meaning as the angle of projection increases, the height of the trajectory also increases.

How does the angle of release affect the horizontal range of a projectile launched with the same initial velocity (assuming no air resistance)?

• A. The higher the angle, the longer the horizontal range.

• B. The lower the angle, the shorter the horizontal range.

• C. The angle does not affect the horizontal range.

• D. There is an angle that produces the maximum horizontal range, typically around 45 degrees.

Answer explanation

The correct answer is D because there is an angle that produces the maximum horizontal range, typically around 45 degrees.
