Examples of Newton's 2nd Law If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.
Explanation:
A 1 kg object accelerated at a constant 5 m/s2. Estimate the net force needed to accelerate the object.
Known :
Mass (m) = 1 kg
Acceleration (a) = 5 m/s2
Wanted : net force (∑F)
Solution :
We use Newton’s second law to get the net force.
∑F = m a
∑F = (1 kg)(5 m/s2) = 5 kg m/s2 = 5 Newton
