What force acted on the objects as they fell on the floor?
The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity.
What causes heavier and lighter objects to fall at different speed?
Because the downward force on an object is equal to its mass multiplied by g, heavier objects have a greater downward force. Heavier objects, however, also have more inertia, which means they resist moving more than lighter objects do, and so heaver objects need more force to get them going at the same rate.
Does size affect air resistance?
Air resistance depends on velocity, area, and shape of the object going through the air. Altitude, temperature, and humidity change air density and, consequently, its resistance. The higher the speed and the bigger the area, the higher the resistance.
What is air resistance affected by?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity. Nonetheless, 1.29 kg/m3 is a very reasonable value. The shape of an object affects the drag coefficient (Cd).
What causes air resistance?
Air resistance, also known as drag, is a force that is caused by air, the force acts in the opposite direction to an object moving through the air. It is where air particles hit the front of the object slowing it down. The more surface area, the more air particles hit it and the greater the resistance.
Does air resistance push up or down?
When you walk you don’t really feel like you are affected by air resistance, but air resistance doesn’t really slow you down. In summary, air resistance force is a push or pull against a motion of an object. Air resistance happens to many large objects, such as cars, aeroplanes and fast moving objects.
Does air resistance slow down?
Friction is a force that opposes the motion of objects; friction can cause objects to slow down. Air resistance is a type of friction. Air resistance causes moving objects to slow down.
Does air resistance increase with mass?
You might think this is because the air resistance force depends on the mass, but you’d be wrong– it’s exactly the opposite. Air resistance is insignificant for heavy objects precisely because it doesn’t depend on the mass. Specifically, the change in motion due to air resistance gets bigger as the mass gets smaller.
How does air resistance affect parachutes?
How large a parachute is (in other words, the parachute’s surface area) affects its air resistance, or drag force. The larger the parachute, the greater the drag force. In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
What is the lowest altitude to open a parachute?
2,000 feet
