When an object changes direction in its motion, its velocity changes, and if the object is accelerating, its acceleration will also change direction. This change in direction is due to the application of a force in the opposite direction. The object's kinetic energy may also change as a result of this change in direction.
What else can I help you with?
How do we determine the direction of the impulse vector?
The direction of the impulse vector is determined by the direction in which the force is applied to an object. It is always along the line of action of the force. The impulse vector points in the same direction as the force on the object and causes a change in the object's momentum in that direction.
How does length contraction occur in relation to an object's motion, with the understanding that it only happens along a direction perpendicular to the object's motion?
Length contraction occurs when an object moves at high speeds, causing it to appear shorter in the direction of its motion. This contraction only happens along the direction of motion, not perpendicular to it.
What happens to the speed of moving object when it is pushed in the direction of motion?
The speed increases. The object accellerates positively in the direction of motion.
What happens to the direction of motion of the ball what changes it direction of motion?
The direction of motion of a ball changes when an external force acts on it, such as a kick or a collision with another object. This force causes the ball to accelerate or decelerate in a different direction than its initial path.
When is displacement at its maximum and velocity equal to zero?
Displacement is at its maximum when an object changes direction, reaching the farthest point from its starting position. Velocity is equal to zero at the moment when an object changes direction, either at the peak of motion in a vertical direction or at the points where an object reverses its direction horizontally.
When the earth ocassionally reverses direction is called what motion?
The earth never reverses direction, nor does any other planet. The APPARENT reversal of direction of some other planets, as seen from earth, is called retrograde motion.

What happens to the speed when acceleration is in the same direction as the motion?
Speed increase constantly.
What happens to the speed of moving abject when it is pushed in the direction of motion?
its speed increases
What is the name given to the phenomenon in which the apparent motion of the planets sometimes reverses?
Retrograde motion happens when the Earth overtakes an outer planet in its orbit. It happens around the date of Opposition when the planet is opposite the Sun in the sky. Usually planets travel from west to east along the ecliptic, but during retrograde motion they travel backwards, from east to west,.
What happens when the electric current is reversed on am electromagnet?
When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
How does the direction of friction compare to the direction of Motion?
By definition, friction is opposite of the direction of motion.
What is the relationship between the direction of torque and the rotational motion of an object?
The direction of torque determines the direction of rotational motion of an object. Torque is a force that causes an object to rotate around an axis, and the direction of the torque applied determines the direction in which the object will rotate.
