Which of the following is a projectile motion?

A stone thrown into the air

Explanation

An object moving under the influence of gravity only.

What is the initial velocity of a projectile at its highest point?

Zero

Explanation

It reaches its maximum height, momentarily stopping.

In projectile motion, the horizontal component of velocity remains _____ throughout the motion.

Constant

Explanation

No horizontal forces act, so the velocity remains constant.

What is the path followed by a projectile called?

Parabola

Explanation

The trajectory of a projectile follows this curve.

What is the angle at which a projectile will travel the farthest horizontally?

45 degrees

Explanation

It balances vertical and horizontal components, maximizing range.

Which of the following is true regarding the acceleration of a projectile?

Acceleration is always in the vertical direction

Explanation

Gravity causes acceleration downward in projectile motion.

What happens to the time of flight of a projectile when the angle of projection is doubled?

It remains the same

Explanation

The component velocities change proportionally.

Which of the following is true for the horizontal component of velocity in projectile motion?

It remains constant

Explanation

No horizontal forces, so no change in velocity.

Which force affects the horizontal motion of a projectile?

Friction

Explanation

Friction or air resistance can affect horizontal motion.

#10

At what angle should a projectile be launched to achieve maximum range?

45 degrees

Explanation

This angle balances vertical and horizontal components.

#11

In projectile motion, what happens to the vertical component of velocity over time?

It decreases linearly

Explanation

Gravity acts against the vertical velocity.

#12

Which equation represents the range of a projectile launched from the ground with initial velocity v at an angle θ?

R = (v^2 cos(2θ)) / g

Explanation

Calculates the horizontal distance traveled.

#13

What is the acceleration of a projectile at the highest point of its trajectory?

Zero

Explanation

The vertical velocity momentarily stops.

#14

For a projectile launched from the ground at an angle θ, when is the range maximum?

θ = 45 degrees

Explanation

The optimum angle for maximum horizontal distance.
