Question

What would you expect to happen to the acceleration if all friction were removed from the ramp?

a) The acceleration would increase.
b) The acceleration would decrease.
c) The acceleration would remain the same.
d) The acceleration would become zero.
e) The acceleration would become negative.

Answer 1

The acceleration of an object sliding down a ramp would increase if all friction were removed because friction opposes motion, and without it, the object would accelerate faster due to gravity alone.

Step-by-step explanation:

When all friction is removed from a ramp, the acceleration of an object sliding down the ramp would increase. This is because friction is a force that resists movement between two surfaces, so without friction, there is less resistance, and the object would accelerate faster under the influence of gravity alone. In physics, the formula for the acceleration down an incline without friction is a = g sin(θ), where g is the acceleration due to gravity and θ is the angle of the incline. Since this formula does not depend on the mass of the object, all objects will experience the same acceleration down a frictionless incline if the angle is the same.
