Question

1. in our experiment, we used a ramp set up much like this one. which statement matches the motion of the glider’s velocity if it rolled down the ramp for 1.5 seconds?

a) the velocity became smaller and smaller as it went down.
b) velocity was the same at the top and bottom.
c) the glider’s velocity increased as it went further down the ramp.

Explanation:

When an object (the glider) rolls down a ramp, it is under the influence of gravity. Gravity causes the object to accelerate down the incline, meaning its velocity (speed in a direction) increases as it moves further down the ramp. Option a is incorrect because velocity should increase, not decrease. Option b is incorrect as the glider starts with some initial velocity (or from rest) and gains speed, so velocity at the bottom is higher than at the top. Option c correctly describes the motion as the glider's velocity increases due to acceleration from gravity along the ramp.

Answer:

c) The glider’s velocity increased as it went further down the ramp.
