What causes an object to reach its terminal velocity?
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.
What is terminal velocity and what causes it?
Terminal velocity is the constant speed that an object reaches when the drag force of the air resistance is equal in magnitude and opposite in direction to the force of gravity acting on the object. This balance of forces causes the object to stop accelerating and fall at a constant speed.
Why does terminal velocity exist?
When an object is falling, it accelerates, so it is speeding up. The faster it goes, the more air resistance there is on the object. Eventually, the force of the air resistance pushing up on the object will equal the force of gravity pushing down on the object. The forces on the object are balanced (they cancel out), so it will have no acceleration. This causes terminal velocity; the object is not speeding up anymore. When the forces on an object are balanced, it has no acceleration. This does not mean it has no velocity, it just means that the velocity is not changing (it does not speed up or slow down.)
Why is the velocity of accelerated body may be zero?
The velocity of an accelerated body may be zero when it temporarily stops moving at a specific point during its acceleration process. This can happen if the body changes direction or experiences a deceleration that causes its velocity to drop to zero before changing again to increase its velocity in the opposite direction.
What is the difference between velocity and force?
Velocity is a measure of an object's speed and direction of motion, while force is a push or pull that causes an object to move, stop, or change direction. Velocity is a vector quantity and includes both speed and direction, while force is a vector quantity that causes acceleration in an object.

When will an object falling earth stop accelerating?

What object moving at 30 ms takes 5 s to come to a stop what is the objects acceleration?
The acceleration of the object can be calculated using the formula: acceleration = (final velocity - initial velocity) / time Given that the final velocity is 0 m/s (since the object comes to a stop), the initial velocity is 30 m/s, and the time is 5 s, the acceleration can be found by plugging these values into the formula.
Can you site an example in which the acceleration of a body is opposite in direction to its velocity?
When an object is thrown upwards, the acceleration due to gravity pulls it downwards, opposite in direction to its initial velocity. This causes the object to eventually come to a stop and reverse its direction as it falls back down.
What is the action of an automobile if the velocity is positive and the acceleration is negative?
it will stop after some time
Can a particle with a constant acceleration stop and be stopped?
Yes, a particle with constant acceleration can come to a stop if its acceleration is opposite to its velocity vector. It can also be stopped by an external force acting against its motion, overcoming its acceleration.
When will an object stop falling toward earth stop accelerating?
at terminal velocity
How can the velocity of a car during breaking at a constant acceleration against time from the moment of applying the breaks?
The velocity of a car during braking with constant acceleration can be calculated using the kinematic equation: final velocity = initial velocity + acceleration * time. As the car brakes, the initial velocity decreases to 0 m/s (assuming the car comes to a stop), and the acceleration due to braking is negative. Therefore, the equation becomes: final velocity = -acceleration * time.
