Both increase the kinetic energy, thus making the crash more destructive.
Friction will reduce an object's speed.
Speed of an object at one instant of time is the object's instantaneous speed.(Not velocity.)
The speed of an object at one instant of time is its instantaneous speed.
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
when you know both speed and direction of an objects motion you know the velocity of an object.
The speed of an object can be found by dividing the distance travelled by the object by the time taken for the object to travel that distance. Speed=Distance/Time
Causes of motion include forces acting on an object, such as pushing or pulling. Effects of motion can vary, such as changes in position, speed, or direction of an object. Motion can also lead to interactions with other objects or changes in energy levels.
The relationship between the speed and mass of an object is that the speed of an object is affected by its mass. In general, the greater the mass of an object, the more force is needed to accelerate it to a certain speed. This means that objects with more mass require more energy to move at the same speed as objects with less mass.
Different objects can have different speeds; also, the same object can have one speed now, and a different speed later.
No, most objects do not travel at a constant speed. Factors like forces acting on the object, changes in direction, and external influences can cause an object's speed to vary. Objects may speed up, slow down, or change direction as they move.
Speed is relative to the speed of light and gravity. So gravity could effect speed.
Objects do not always travel at a constant speed. Acceleration and deceleration can cause changes in an object's speed. In real-world scenarios, factors like friction, air resistance, and gravity can affect the speed of an object as it moves.
