acceleration due to gravity lab answers falling object

When we divide by each of their masses though, object 1 will have an acceleration of 5g N/ 5 kg = g m/s 2 while object 2 will have an acceleration of 2g N/ 2 kg = g m/s 2. We can see from this equation that even though a heavier object will experience a stronger force due to gravity, its acceleration will be the same as the lighter one since the force is also divided by the mass of the object.įor example, if I have an object 1 that is 5 kg and an object 2 that is 2 kg, let's say that the heavier object will experience g*5 = 5g N of force from gravity while the lighter one experiences g*2= 2g N of force. If we think of Newton's second equation: Force/mass= acceleration. However, this doesn't not mean that either object will fall faster. That equation tells us that a heavier object is pulled more by gravity than a lighter one, which is why it's harder to pick up a heavier object than a lighter one. On earth, that constant is given the letter g= 9.8 m/s 2. The force that gravity exerts on a falling object is proportional to its mass (Force = a constant number * mass). Hello Aiden, your question is a good one and is one of the most commonly misunderstood ideas in physics and gravity-related concepts. If the lighter object is small, and the heavier object is big, however, we would have to figure out the density and area of resistance of each one before we can say which one falls faster, still assuming that they start out with the same falling speed. If we assume that a lighter and a heavier object both start to fall at the same speed, have the same shape, and are the same size, then the heavier object will fall faster because it would be denser. How much air resistance there is depends on a few things:Ģ) what the area on the object that air resistance is 'dragging' (in many cases it's the area going against the air) and However, if two things are falling through the atmosphere of the Earth, the force from air resistance would also act on the things and slow them down. In other words, if two things were falling through vacuum at the Earth, these two would fall toward the Earth at the same speed because Earth's gravity is the only force acting on the two. If two things are falling through a vacuum, they would have the same speed toward whatever object they approach because gravity would be the only force on the two things. The gravitational acceleration for all objects is the same. The air friction can make a difference, but in a rather complicated way.

No, heavier objects fall as fast (or slow) as lighter objects, if we ignore the air friction. A hammer and a feather on earth would probably fall at different speeds due to air resistance however, if you had two balls of the same size, but one light and one heavy, you would see the same effect. One of the astronauts dropped a hammer and a feather on the moon, and they fell at the exact same speed! You can see the video here. This fact was experimentally confirmed when the astronauts on the Apollo 15 mission went to the moon. The acceleration due to gravity is about 10 m/s 2 everywhere around earth, so all objects experience the same acceleration when they fall.Īcceleration is the change in speed in a second, so if all objects have the same acceleration, they experience the same change in speed. Heavy objects fall at the same rate (or speed) as light ones. Do heavier objects fall faster than lighter objects?
