4) Weight is the gravitational force on an object.
a)True
b) False
5)Two carts of mass 1000g and 500g respectively have the same net force exerted on them. Which has larger acceleration?
a)Halved
b)Tripled
c)Reduced by 1/3
d)Need more info
Explanation / Answer
1. false
------------------------------
2. true
force F = ma = M(V/t)
so greater the spped, greate the force
so answer is true
-------------------------------------------
3. option b tripled
as Weight W = mg
---------------------------------
4. true
---------------------------------------
5. lesser mass 500 gms
