What acceleration does a rocket need to reach speed of 200 m/s at height of 1.0km. I know that acceleration is velocity over time but I have only velocity and distance.
Acceleration is the rate at which the velocity of an object changes over time. It is a vector quantity, meaning it has both magnitude and direction.
Acceleration can be calculated by dividing the change in velocity by the change in time. This can be represented by the formula a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Positive acceleration occurs when an object's velocity is increasing, while negative acceleration (also known as deceleration) occurs when an object's velocity is decreasing. Positive acceleration is often associated with speeding up, while negative acceleration is associated with slowing down.
Newton's second law of motion states that the net force acting on an object is directly proportional to the object's mass and acceleration. This means that the greater the force acting on an object, the greater its acceleration will be if its mass remains constant.
Yes, acceleration can be negative. This occurs when an object is slowing down or decelerating. It simply means that the direction of the acceleration is opposite to the direction of the velocity.
