Vector A and B

What is true about vector A and B as you see them above?

Magnitude includes the number and a unit.  Since no numbers are involved the length of the arrow represents the magnitude.  The directions are pointing the same way but the lengths are different.

Vector A and B

What is the maximum magnitude of vector A and B in any arrangement?

Magnitude includes the number and a unit.  Since no numbers are involved the length of the arrow represents the magnitude.  The directions are pointing the same way but the lengths are different.

Vector Minimum Maximum and Right Angle

Maximum is B + A or A + B

2D Projectile Motion Quiz

Projectile Motion Basics Quiz

Do you know your projectile motion facts?

Projectile Motion

Find out by taking our quiz

1 / 10

A ball is thrown horizontally at 20 meters per second and takes 1.3 second to hit the ground.  What happens to the time the object takes to fall if thrown much faster at 45 m/s?

The X and Y motion are independent.  No matter how fast forward something is thrown, in the Y axis the object acts like it's falling.  On earth an object falling from the same height would take the same time to hit the ground no matter how fast forward it is thrown or if it is just dropped.  (ignoring air resistance)

2 / 10

What angle would you throw a ball to get the furthest X axis distance?

45 degrees the furthest downrange

3 / 10

What angle would you throw a ball to get the greatest Y axis distance?

45 degrees the furthest downrange

The greater the angle to the horizontal the further up but less downrange.  Directly up or 90° would get you the greatest height (Y axis distance)

4 / 10

If a ball is thrown with a Y component of velocity of 30 m/s what is its Y component of velocity at the top of its flight path?

The acceleration in the air is always 10 m/s2 down.  This is how much velocity is changing every second.  After three seconds starting from a velocity of 30 m/s up the ball has a velocity of 0 m/s at the top.  The acceleration is still 10 m/s2 down, so one second later the ball would be going 10 m/s down, and 20 m/s down a second after that, then 30 m/s down when returning to the same height.

5 / 10

If a ball is thrown with a Y component of velocity of 30 m/s what is its acceleration at the top of its flight path?

The acceleration in the air is always 10 m/s2 down.  This is how much velocity is changing every second.  After three seconds starting from a velocity of 30 m/s up the ball has a velocity of 0 m/s at the top.  The acceleration is still 10 m/s2 down, so one second later the ball would be going 10 m/s down, and 20 m/s down a second after that, then 30 m/s down when returning to the same height.

6 / 10

If a ball is thrown with a Y component of velocity of 30 m/s what is the magnitude of Y component of velocity when it returns to the same height?

The acceleration in the air is always 10 m/s2 down.  This is how much velocity is changing every second.  After three seconds starting from a velocity of 30 m/s up the ball has a velocity of 0 m/s at the top.  The acceleration is still 10 m/s2 down, so one second later the ball would be going 10 m/s down, and 20 m/s down a second after that, then 30 m/s down when returning to the same height.

Magnitude means just the number and not the direction so 30 m/s when it returns to the same height.

7 / 10

If a ball is thrown with a 7 m/s X component of velocity, what is the magnitude of X component velocity if still in the air after 1.3 seconds?

In projectile motion only the Y component of velocity is accelerated.  The X component is in constant motion.  If it was 7 m/s at the beginning it is still 7 m/s anywhere in the air unchanged.

8 / 10

What is the actual speed of a ball is thrown with an X component velocity of 7 m/s forward and a Y component of velocity of 30 m/s up?

Actual speed would be the hypotenuse of the two vectors placed head to tail.  You would do the Pythagorean Theorem.

The direction does not matter because it asks for speed which is a scalar.

actual speed

9 / 10

What is the actual speed of a ball is thrown with an X component velocity of 7 m/s forward and a Y component of velocity of 30 m/s up when at the top of it's flight path?

At the top of a flight path the y component of velocity is 0 m/s temporarily so speed is only made up of the horizontal component.  So 7 m/s here.

Projectile Motion

10 / 10

In the pilots perspective, how does a package dropped from a plane look like it falls? (Neglecting air resistance)

Projectile Motion Pilot View From Stickman Physics

The package appears to fall straight down because the X component of velocity of the plane and package are the same.
