## Why is acceleration inversely proportional to mass?

As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, mass is inversely proportional to acceleration.

## Did changing the mass of the cart change its speed at the end of the incline does this make sense explain?

No, the mass did not change because the slope is still going downwards, thus why the cart speed is the same as it was before. No, because the speed of the cart is not affected by its weight.

## How does mass of a cart impact the result of a collision?

When cart B is weighted, it has a greater inertia and moves more slowly after the collision, while cart A rebounds in the opposite direction. Momentum of the system is conserved in both cases, with the lighter cart’s velocity being greater after impact due to its mass being less than the cart which has weights.

## What causes an object to slow down after no longer being pushed?

We know that one force which causes objects to slow down or stop is friction.

## Why are fan CART experiments done on a leveled track?

The purpose of the fan cart demonstration is to show students that a constant force implies a constant acceleration.

## How do you think changing the mass of the cart will affect its acceleration?

Yes 3. Form hypothesis: A. How do you think changing the mass of the cart will affect its acceleration? Changing the mass of the cart will lower the acceleration of the cart.

## How does a fan cart work?

A large fan is placed on a cart with low-friction wheels. The fan is turned on and the cart moves backward, as expected. If a large “sail” (rectangular card) is attached so that the air from the fan strikes it perpendicularly, the system will not move.

## How do you find acceleration with two velocities and distance?

Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .
