I think that would be true in the absence of friction.jaguar___ said:
You can say anything you want. Does it make sense in the context of the situation?jaguar___ said:
Free fall is the motion of an object under the sole influence of gravity, where the object is not in contact with any surface. Sliding, on the other hand, refers to the motion of an object along a surface due to the force of friction. In free fall, an object will always accelerate towards the ground at a constant rate of 9.8 m/s^2, while the acceleration of an object sliding depends on the surface and the force of friction.
Yes, an object in free fall will always gain speed as it falls due to the constant acceleration of gravity. This means that the object's velocity will increase by 9.8 m/s each second it falls.
Air resistance, also known as drag, can decrease the speed gained during free fall. As the falling object moves through the air, it experiences a force in the opposite direction of its motion, which can slow it down. However, the effect of air resistance is relatively small for most objects in free fall.
No, an object cannot reach terminal velocity while sliding. Terminal velocity is the maximum speed an object can reach while falling through the air, and it only applies to objects in free fall. When an object is sliding, it is in contact with the surface and is not falling through the air, so it cannot reach terminal velocity.
The mass of an object does not affect its speed during free fall. According to the law of gravity, all objects fall at the same rate regardless of their mass. However, the mass of an object does affect the force of gravity acting on it, which in turn affects the object's weight and the force of friction acting against it while sliding.
