Constant velocity is the speed at which an object moves in a straight line without changing direction. In the context of crates, it refers to the consistent speed at which a crate is moving without any changes in direction or acceleration.
Newton's first law of motion states that an object will remain at rest or in constant motion at a constant velocity unless acted upon by an external force. This applies to crates as well - if no external force is applied, the crate will continue to move at a constant velocity.
Yes, constant velocity can be calculated by dividing the distance the crate travels by the time it takes to travel that distance. This will give you the average speed at which the crate is moving.
According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Therefore, a crate with a larger mass will require more force to maintain a constant velocity compared to a smaller crate.
Friction is a force that opposes the motion of an object, so it can impact the constant velocity of a crate by slowing it down. In order to maintain a constant velocity, an equal and opposite force must be applied to counteract the force of friction.
