What is the effect of the mass of an object at the time of descent.?
According to Galileo, the mass of an object has no effect on the time of descent here on earth under a constant gravitational value, he discovered that objects will reach the ground at the same even though they may have different masses. this is due to the same rate of acceleration of objects experienced here on earth (approximately 9.8m/s/s). Merely the minute difference in the time observed between two falling objects of different masses can be attributed to the heavier object overcoming the friction force of air resistance better than the lighter.
An impulse is the product of the on an object and the time during which it is applied?
What happens when an impulse acts on an object? Impulse is defined as force acting on an object for a specific time. Impulse = Force * time If you push on a object for a specific time, the object's velocity will change. Equation = F* t = mass * ∆ v This equation is derived from F = m* a, a = ∆v ÷ t
How do you increase the time of descent of a freely falling body?
*by reducing the weight or density of the falling object. *By introducing resistance to the falling object in the form of flat light weighted object. *giving parachute.
Which of the following can be used to measure an object's motion?
Nothing on that list has any effect on an object's motion.
Does gravity exert the same force on all falling objects?
No. Gravity can be thought of as a force, but that is due to its effect on anything that possesses mass and/or energy. The effect that gravity exerts on any object is proportional to the amount of mass that is responsible for the presence of gravity and is also proportional to the amount of mass possessed by the object experiencing that gravitational presence. Therefore a gravitational field will exert a greater 'force' on a greater mass. However, mass also possesses the characteristic of inertia, which is a measure of resistance to any change to a state of motion - which effectively is a resistance to the effect of gravity. Inertia is also proportional to mass. What this means is that the greater the mass, the greater the pull it experiences due to gravity but at the same time, the greater is its resistance to that pull. Hence all falling objects experience the same acceleration due to the effect of gravity which is not the same as the force. All objects fall at the same rate. ========================= (Note: Gravity does not exert the same force on all objects, which is the reason why big people "weigh" more than smaller people do on the same planet.)
What would the hypothesis be for Does the mass of an object affect the falling time you have not tested it?
Before you test it, you could state the hypothesis in two different ways You could say: "The mass of a falling object has no effect on the time it takes to fall some distance." Or you could say: "The time a falling object takes to fall some distance depends on its mass." You could use the same tests to investigate EITHER hypothesis. --------------------------- The mass of a falling object has no effect on the time it takes to fall some distance assuming zero air resistance.
What equation is used to caculated the velocity of a falling object?
If the object is falling in vacuum, then its direction is downward, and its speed at any time is Speed = (speed when time started) + [(acceleration of gravity) x (number of seconds since time started)]. If the object is falling through air, water, or some other fluid, then the formula is much, much more complicated. It involves the object's mass and shape, and the properties of the fluid it's falling in.
What occurs only when air resistance does not affect the motion of a falling object?
The mass of an object will not affect the time it takes for it to reach the ground from a fixed height. Backspace
Is the speed and acceleration of which an object fall always the same?
Without air in the picture, gravity causes all falling objects to accelerate at the same rate, and grow their speed by the same amount after the same amount of time, regardless of their size, mass, or weight. We never see this in daily life, because anything we see falling is falling through air. The effect of air resistance on a falling object depends on the object's weight, size, shape, and speed, so its behavior in response to gravity alone is obscured.

What is the effect on periodic time of doubling the mass of the vibrating systems?
there is no effect of mass on time period because mass and time period are inversely proportional
How do you find the speed of an object falling with distance and time?
Speed = distance / time.
What objects are not affected by force?
There is no such object. Any object on which a force is applied will accelerate (i.e., its velocity will change over time). If the object has a very large mass, the effect will be hardly noticeable for any given force.
How is velocity of a falling object related to the length of time the object falls?
Velocity increases but not infinitely.
Which of the following can be used to measure an object's motion?
Nothing on that list has any effect on an object's motion.
