Why does it take more force to accelerate a more massive object?
A force will not increase or decrease an acceleration. If the force is constant, it will cause a constant acceleration. It may increase or decrease the speed. The change of velocity - for the same force - is the same, whether the speed is increasing, decreasing, or just changing direction.
How far does a 100 newton force have to move to do 1000 joules of work?
Use the definition of work: work = force x distance and solve for distance. Since you are using SI units, the distance will be in meters. Note that this is a simplified formula, which assumes (1) that the force is constant, and (2) that the force is applied in the same direction as the movement.
Why is mass not important?
There is no reason why mass is not important. The reason for saying that is that mass is very very very important for a lot of reasons. Everything has mass, so mass is part of everything that is important. Only ideas do not have mass, but a lot of people think that a lot of ideas have weight. Also without mass gravity would have nothing to pull on and we would not know that gravity was there. So you can see that mass is important and I hope that you will not make this same mistake again to think that it is not important.
What is always true of an object with a lot of mass?
Such an object makes a larger dent in the fabric of space-time than an object with little mass. (It has a greater gravitational attraction than less massive objects)A greater force is required to accelerate such an object than a less massive object
If an object has a large mass on Earth what else does it have a lot of?
Answer: weight and inertia
What would you expect to accelerate most?
A small mass with a lot of force applied.
How does mass affect distance when the force applied is the same?
well think of it like having a small object with little mass then a large object with a lot of mass. Hitting the big object takes more force to make it move and the little object does not take nearly as much force to make it move. i hope this helped!
What was Isaac newtons 2 rule?
The second law is about how the force affects the motion. A relatively small force could make, say, a tennis ball accelerate a lot (e.g. changing its direction completely), but could not make the motion of, for example, a truck change very much. This is because the mass of the objects are very different. Similarly, if two objects had the same mass, a large force would change the motion a lot, where as a small force not so much. So the change in motion depends on the size of the force and the mass of the object.
How does gravitational force affect your mass?
Gravitational force does not change your mass. Mass is the same when you are floating in the weightlessness of space, but your mass when put into a gravitational field creates your weight. On Earth, Earth's gravity (gravitational force) pulls on your mass, creating your weight. The mass of an object determines its gravitational pull. A object with a lot of mass like the Earth has a lot of gravitational force/pull -- the force we call gravity. So, your body has a gravitational force, it's just so small, because your mass is small, it isn't noticeable.
Why does a rocket takes a lot of force?
A Rocket has a LOT of MASS. Its initial Velocity is ZERO and its final velocity must be approximately 25,000 MPH to get into Orbit. That takes a LOT of Acceleration! FORCE = MASS x ACCELERATION FORCE = 1/2 MASS x V2 (the 2 means squared) Looking at these equations you can see that requiring a High amount of Acceleration, and a LARGE terminal Velocity acting on a HUGE Mass, will require a "lot of FORCE". It is simple Arithmetic!
Would you expect a small mass with a lot of forced applied to accelerate the most?
No, think about throwing a piece of paper, it just fluters down, but a tennis ball goes a long ways
Why does an object with a lot of mass take the shape of a sphere?
Objects such as astriods or small moons are iregulary shaped because they have much less mass than the planets. Therefore thier gravitational force is not strong enough to form a sphere.

When a substance has a lot of mass packed into a small volume it is said to be?
Dense
The distance between two objects increase what happens to the force of gravity between them?
The force changes in the direction opposite to the change in distance. More distance ==> less force, and less distance ==> more force. That's why the gravitational force between the sun and you is small, even though the sun has a lot more mass than the earth has.
What happens to the force of gravity between two objects if the distance between them increased?
The force changes in the direction opposite to the change in distance. More distance ==> less force, and less distance ==> more force. That's why the gravitational force between the sun and you is small, even though the sun has a lot more mass than the earth has.
How can a object have a lot of mass but a little volume?
Volume x density = Mass A material with high density has a great mass for a small volume.
