How do projectiles travel vertically? (reason, acceleration, type of motion, equation)

Front

Reason: gravity acceleration: 9.8 m/s2 down type of motion: UAM equations: UAM equations

Back

How do projectiles travel?

Front

Horizontally and vertically at the same time.

Back

How does velocity change when launched at an angle?

Front

becomes vector resolution, Vy=Vi sin theta Vx = Vi cos theta

Back

How do projectiles travel horizontally? ( reason, acceleration, type of motion, equation)

Front

Reason: inertia acceleration: zero type of motion: constant velocity equation: Vx=Dx/t

Back

What is a projectile?

Front

Anything that is hit, kicked, thrown, etc, into the air without self propulsion.

Back

What are the implied givens for horizontal projectile motion?

Front

Viy=0, g=-9.8m/s2

Back

When does Dy = 0

Front

when motion starts and stops at the same level

Back

If two balls are thrown off a cliff, one horizontally and the other dropped, which one will hit the ground first?

Front

Same time because gravity acts on them identically.

Back

Remember - symetry

Front

Viy=-Vfy f dy is zero

Back

Which angle has the best range?

Front

45

Back

What links the horizontal and vertical motion

Front

Time, so it doesn't have a subscript

Back

What happens to the velocities when you use the complementary angles?

Front

Vx and Vy switch
