Motion in 2 Dimensions

Front

What is the formula to calculate time (t) when given final velocity (Vf), initial velocity (Vi), and acceleration (a)?

Back

t = (Vf - Vi) / a

Front

How do you calculate the range (d) of a projectile given its speed (s) and time (t)?

Back

d = s x t

Front

What is the vertical acceleration of a projectile due to gravity?

Back

-9.8 m/s²

Front

At what position will the magnitude of the vertical velocity be 0 m/s during projectile motion?

Back

At the peak of its trajectory.

Front

What happens to the vertical velocity of a projectile as it ascends?

Back

It decreases until it reaches 0 m/s at the peak.

Front

What happens to the vertical velocity of a projectile as it descends?

Back

It increases due to the acceleration of gravity.

Front

What is the significance of the negative sign in the vertical acceleration due to gravity?

Back

It indicates that the acceleration is directed downward.

Front

How do you calculate the time of flight for a projectile launched vertically?

Back

t = 2 * (Vi / g) where g is the acceleration due to gravity.

Front

What is the effect of air resistance on projectile motion?

Back

It reduces the range and alters the trajectory.

Front

What is the difference between horizontal and vertical motion in projectile motion?

Back

Horizontal motion is uniform (constant velocity), while vertical motion is accelerated (due to gravity).
