An object falling towards the Earth will stop accelerating once it reaches its terminal velocity, which is the maximum speed it can achieve due to air resistance. This happens when the force of air resistance is equal to the force of gravity acting on the object.
To keep a sled accelerating downhill, the force of gravity must be greater than the force of friction acting against the sled. This allows gravity to overcome the frictional force and propel the sled forward.
at terminal velocity
A falling object stops accelerating when it reaches its terminal velocity, which is the maximum speed it can reach due to air resistance. At this point, the force of gravity pulling the object downwards is balanced by the force of air resistance pushing upwards, resulting in a constant velocity.
When the only force on an object is the force of gravity,we say that the object is in "free fall".
If nobody pushed it, then it had to be either gravity or the wind.
An accelerating force is a force that causes an object to change its speed or direction of motion, resulting in acceleration. It can be exerted by various means, such as gravity, friction, or propulsion systems, and its magnitude is directly related to the object's acceleration according to Newton's second law of motion.
An object reaches its terminal velocity when the force of air resistance equals the force of gravity pulling it down. This balance of forces causes the object to stop accelerating and fall at a constant speed.
Terminal velocity- When a falling object is no longer accelerating; the force due to gravity is equal to the opposing force of air resistance.
When the only force acting on an object is gravity, the object is in free fall. This means that the object is accelerating towards the Earth solely due to gravity, with no other forces opposing its motion.
Yes, when a sled is accelerating downhill, the force of gravity pulling the sled downhill must be greater than the normal force acting in the opposite direction to overcome friction and any other resistive forces. This difference in force is what allows the sled to accelerate downhill.
When the only force affecting an object is gravity, the object is in free fall. This means that the object is accelerating solely due to the force of gravity, falling towards the Earth without any other forces acting upon it.
