Front

What two factors affect the range of a projectile?

Back

Launch angle and Launch Velocity.

Front

At what point is v_y = 0 m/s?

Back

Point B.

Front

What is the only force acting on a projectile?

Back

Gravity.

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where v is tangential velocity and r is radius.

Front

Calculate the centripetal acceleration for a toy car with a radius of 1.2 m and a tangential velocity of 1.8 m/s.

Back

2.7 m/s^2.

Front

What is the formula for centripetal force?

Back

F_c = m * a_c, where m is mass and a_c is centripetal acceleration.

Front

Calculate the centripetal force for a softball pitcher rotating a ball with a velocity of 3 m/s, mass 0.12 kg, and radius 0.65 m.

Back

1.66 N.

Front

What is the effect of launch angle on projectile motion?

Back

It determines the height and distance traveled by the projectile.

Front

Define projectile motion.

Back

Motion of an object thrown into the air, subject to gravitational acceleration.

Front

What is the relationship between launch velocity and range in projectile motion?

Back

Higher launch velocity increases the range of the projectile.
