True/ False questions
A) During the collision of a car with a large truck, the truck exerts an equal size force on the car as the car exerts on the truck.
B)If two object have the same acceleration, they are under the influence of equal forces
C)An object's velocity will change if a net force acts on the object
D)The net force which acts on an object which maintains a constant velocity is zero
E)If a net force acts on an object, the object's speed will change.
F) A bicycle initially moving at a constant velocity will slow down unless a small net force is applied

It doesnt tell me what is wrong any help appreciated
Explanation / Answer
a) is true, 3rd law of motion
b)false , because if mass is different then same force will produce different acceleration
c) is true, 2nd law of motion
d)is true, 2nd law of motion
e) false. The object could have a constant speed but a changing direction which would require a force to be applied, a great example is uniform circular motion
f)false. A bicycle moving on a road in air needs a small net force to counter road and air friction (this is why you must constantly use fuel despite driving in a straight line at constant speed). One moving in empty space in a vacuum would not.
