# Acceleration/Momentum problem

1. The problem statement, all variables and given/known data Use the concepts of momentum and Newton’s second law to explain why a motorcycle can accelerate at a greater rate than a large truck.

2. Relevant equations

3. The attempt at a solution
The motorcycle will accelerate at a greater rate because of the truck has a greater mass (greater resistance to a change in speed.) This increased rate of acceleration is mathematically proven by the formula a= F/m, which states acceleration is inversely proportional to the mass.

I'm not sure how to add momentum into this paragraph. Is this answer good enough?

Can you link momentum with Newton's 2nd law?

I'm not sure how to.

Momentum is defined as mass times velocity.
Acceleration is defined as the change in velocity divided by the change in time.

net force = mass times acceleration
