Physics Unit 1 Quiz 5 explores concepts of projectile motion and vector properties. Questions cover vector size, acceleration in projectile motion, and velocities at various points.
Upward
Dependent on the initial velocity
Downward
At a 45 O angle
Rate this question:
The velocity and acceleration are both zero
The x-velocity is zero and the y-velocity is zero
The x-velocity is non-zero and the y-velocity is zero
The velocity is non-zero and the acceleration is zero
Rate this question:
Depends on initial velocity
Depends on how long it is in the air
0 m/s2
Depends on y-acceleration
Rate this question:
Opposite
Unable to determine
Equal and opposite
Equal
Rate this question:
Just after it is tapped by the player.
At the highest point of its path.
Just before it strikes the ground.
When the horizontal and vertical components of its velocity are equal.
Rate this question:
The horizontal velocity is constant
The vertical acceleration is upward during the first half of the flight, and downward during the second half of the flight.
The horizontal acceleration is zero.
The vertical acceleration is 9.81 m/s2 down.
The time of flight can be found by horizontal distance divided by horizontal velocity.
Increase then decrease
Decrease then increase
Remain unchanged
Increase only
