What affects the speed at which objects fall through the air?
Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
What makes objects fall at different rates in the air?
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.
What two forces affect the rate at which an object falls?
Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object.
What factors affect the rate of 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.
Why do a bowling ball and feather fall at the same rate?
The feather will drift breezily to the ground while the bowling ball plunks downward immediately. The feather-bowling ball duo doesn’t fall at a slower rate because the feather is lighter than just the bowling ball alone — instead, they both fall at exactly the same rate.
Which force would cause an object to fall?
The force of gravity
When the only force acting on an object is gravity, the object is said to be in free fall. The force of gravity causes the object to accelerate. Free fall is motion where the acceleration is caused by gravity.
What factors affect speed physics?
speed
- Speed is directly proportional to distance when time is constant: v ∝ s (t constant)
- Speed is inversely proportional to time when distance is constant: v ∝ 1t (s constant)
What are the two factors that affect the acceleration of an object?
The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
