Projectile Motion

Front

What is the vertical acceleration of a projectile when neglecting air resistance?

Back

9.8 m/s²

Front

If a ball is thrown straight up and takes 4 seconds to reach the peak, how long will it take to return to the original position?

Back

4 seconds

Front

At the highest point of a projectile's path, how does its speed compare to points at the same height?

Back

Speed at the highest point (Q) is less than at points P and R (v_Q < v_R = v_P).

Front

How fast is a dropped object going after 2 seconds?

Back

19.6 m/s

Front

At what point in projectile motion is the horizontal velocity (v_x) equal to 0 m/s?

Back

None of these points.

Front

What is the shape of the path followed by a projectile?

Back

A parabolic path.

Front

What is the effect of air resistance on projectile motion?

Back

It reduces the range and alters the trajectory of the projectile.

Front

What is the formula for calculating the time of flight for a projectile launched vertically?

Back

Time of flight = 2 * (initial velocity / g), where g = 9.8 m/s².

Front

What is the relationship between the horizontal and vertical components of a projectile's motion?

Back

They are independent of each other.

Front

What happens to the vertical velocity of a projectile at its peak?

Back

The vertical velocity is 0 m/s at the peak.
