What are the kinds of motion according to the change in direction and change in speed?
Acceleration is a change in speed or direction. Velocity is the speed and direction. ex. 41 mph northeast
What will happen when you exert force on an object that is in motion?
Its speed, or direction, or both, change. That's called "acceleration".
What must happen for an obect at rest to move or change its speed?
A force must be applied to that object according to Newton's First Law of Motion in order to change the speed and its direction.
Higher speeds require more space for a maneuver?
Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.
Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
What is a change in velocity or direction?
Any change in speed or direction is a change in velocity. That's an acceleration,and it directly implies the presence of force, since it can't happen without force.
What change speed and direction depending on the density and materiel they travel through?
Waves.

Why does a change of speed produce a change in direction?
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)

How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.
Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
A situation in which you can accelerate even though you speed does not change?
"Acceleration" means a change of speed or direction of motion, or both.If you change direction ... like turning a corner ... then there is acceleration,even though your speed is constant.Anything traveling on a circular track, even at a constant speed, has constantacceleration.
What must happen for an object that is already moving to change its speed or direction?
a(n) unblanced force must act on the object
A situation when you can accelerate but the cars' speed doesn't change?
"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.
