This is true. Newton's 2nd law gives us the equation F_net = ma, where m is mass in kilograms and a is acceleration in m/s/s (also m/s^2). 1 kg m/s^2 = 1 Newton (N).
Example: What is the net force if a 6.0 kg mass is accelerated at 4.0 m/s^2?
Answer: F_net = ma = 6.0 kg x 4.0 m/s^2 = 24 kg m/s^2 = 24 N
Yes, it True if you know an object's mass and acceleration you can determine the net force being exerted on the object?
True.
False
false
The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.
Yes. In the formula P=mv, momentum, which governs the force of the impact, is equal to the mass of the object multiplied by the velocity. As the velocity increases, so does the momentum, therefore the greater the height dropped from, the greater the force of impact.
no, they fall the same acceleration ( one gravity ) neglecting air resistance; however they may reach different velocities with air resistance.

acceleration
The acceleration is the same for all objects, as long as air resistance is insignificant. After a while, different objects will have different amount of air resistance. Also, even without air resistance, the speed depends not only on the acceleration, but also on how how long the objects are falling.
Yes, objects can accelerate at a rate greater than "g". Most objects, when falling in the absense of air resisitance, accelerate at a uniform rate of -9.81 m/s^2 (this is under ideal conditions on Earth). Air resistance tends to decrease that acceleration. The classic example of greater than "g" acceleration is a bungee jumper.
The one that was dropped from the higher floor cause freefalling objects get faster and faster with more flight time
AHHH
-- both are related to measurements of motion of objects -- acceleration is the rate at which velocity changes
