Forces True and False?

Question

If a net force acts on an object, the object's velocity will change.
In order not to slow down, a car moving at a constant velocity needs a small net force applied.
During the collision of a car with a large truck, the truck exerts a greater force on the car than the car exerts on the truck.
The net force which acts on an object which remains at rest is zero.
If an object's speed does not change, no net force is acting on the object.
If two objects are under the influence of equal forces, they have the same acceleration.

i thought it was T, F, F, T, F, T But i seem to be \going wrong somewhere...help point me in the right directon please?

Answer 1

Your last two answers are wrong.
If an object's speed does not change, no net force is acting on the object. ----Remember Newton's first Law?
If two objects are under the influence of equal forces, they have the same acceleration. ---Recall Newton's third Law? F=ma, the two objects may not have the same mass.

Answer 2

yeah, i think it shld be: T,F,F,T,T,F
if an object's speed does not change, no net force is acting on the object............. True.
it's just like driving a car ( i think), if u dont push the gas pedal, u probably wont increase your speed.
and for the last one,
they'll have the same acceleration only if you're assuming their masses are the same.
