Why do things move in a straight line in space?

Things in space have inertia. That is, they travel in a straight line unless there is a force that makes them stop or change. Gravity is an important force that can change the course of bodies in space or pull them off of one course, or even cause them to crash together.

What factors affect the fall of the object?

Drag and gravity are two factors that affect the rate an object falls through air. If the gravity (relative to Earth’s gravity) is greater, the rate would change very quickly from slow to fast, but if the gravity is weaker, it would change slower. Drag slows down an object depending on it’s aerodynamics.

Why do heavier objects fall faster?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. Air resistance causes the feather to fall more slowly.

Why mass does not affect free fall?

The mass of an object does not depend on the location, the weight does. An object that moves because of the action of gravity alone is said to be free falling. So all objects, regardless of size or shape or weight, free fall with the same acceleration.

Do satellites go in a straight line?

Initially, the satellites were seen to be stretched out in a straight line measuring roughly 5 to 8 degrees in apparent length. Your clenched fist held at arm’s length is roughly equivalent to 10 degrees, so the satellite train currently measures roughly just less than a fist in length as it moves across the sky.

Why do things fall?

Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Objects with more mass have more gravity.

Why do all objects fall at the same speed?

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth’s surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

Why do objects in space travel in a straight line?

That is, they travel in a straight line unless there is a force that makes them stop or change. The movement of things in space is influenced by gravity. Gravity is an important force that can change the course of bodies in space or pull them off of one course, or even cause them to crash together.

Why can’t I Walk in a straight line?

If you feel unbalanced and can’t seem to walk in a straight line, it could be as a result of a more serious problem. This includes: Stroke – If the symptoms of dizziness and imbalance are sudden, and if you are also experiencing numbness, weakness, speech problems, or vision problems, go to the E.R. immediately.

Why do two objects with the same weight fall at the same time?

The reason for the two behavior of the same objects accounts for the forces acting on it. When you drop a 5 kg body and another 25 tonne body vertically downwards, they will fall under the influence of gravity alone and both will fall with the same acceleration g (free fall). In such a case the weight of the body is zero.

Why do heavier objects fall faster on hills than lighter objects?

Why do heavier objects fall faster on hills but not in straight drops? All other things being equal, if a heavier object will roll at a higher speed down hill than a lighter one, because it’s heavier with more mass, then how is it that dropped objects fall at the same speed regardless of their weight?
