In the context of relative motion, if vBA is the velocity of frame B relative to frame A, what does vBA = 0 imply?
Frame B is stationary with respect to frame A.
For a ball thrown vertically upwards with an initial velocity of 30 m/s, what is the maximum height it reaches?
$45$ m
In projectile motion, what is the equation for the range (R) of an object projected at an angle A to the horizontal?
$R = \frac{u^2}{g}\sin(2A)$
For the position function x(t) = $2t^2 + 4t + 3$m, what does this function represent?
The horizontal position of the projectile.
What is the displacement of a train between t1 = 1.0 s and t2 = 3.0 s if its position function is x = 10 + 3t^2?
$30$ m
For an object in uniform circular motion, what is true about its acceleration?
Acceleration is always directed towards the center of the circle.
What does it mean when the velocity-time graph for an object is a horizontal line at zero velocity?
The object has stopped moving momentarily.
If a ball is thrown vertically upwards, what can be said about its velocity at the maximum height?
Velocity is zero.
What does the term vPB represent in the context of relative motion?
The velocity of frame P relative to frame B.
Explore the concept of projectile motion and learn about its horizontal and vertical components. Understand why the horizontal velocity component remains constant throughout the motion. Discover how gravity affects the projectile's vertical velocity component.
