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 happens to the horizontal velocity of a projectile as it travels along its path?

Back

The horizontal velocity stays the same.

Front

What is the velocity of a projectile at its highest point when tossed vertically upward?

Back

0 m/s

Front

How do you calculate the time (t) it takes for an object to fall a certain distance (d) under gravity?

Back

t = √(d / (1/2)a) where a = 9.8 m/s².

Front

If a coin is tossed vertically upward and reaches its highest point in 7.0 seconds, what is the velocity at that point?

Back

0 m/s

Front

What is the initial velocity of an object if it is thrown horizontally from a height of 6 m and lands 2 m away?

Back

1.82 m/s

Front

How do you calculate the distance (d) a projectile travels horizontally if you know its speed (s) and time (t)?

Back

d = s x t

Front

What is the effect of air resistance on the motion of a projectile?

Back

Air resistance opposes the motion, reducing the range and altering the trajectory.

Front

What is the acceleration due to gravity (a) near the surface of the Earth?

Back

9.8 m/s²
