Is acceleration due to change in direction?
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
What must be applied to an object to change its direction?
Forces cause motion or the change in motion.
What term would describe someone who has the ability to change the direction of his body quickly?
To change abruptly from one direction to another, not only must you have a high rate of change of speed (acceleration), but you must also have a high rate of change of acceleration, called jerk (also known as jolt). Therefore, you would say Tim has a lot of jerk.
How is a change in an object's direction related to the applied force?
In order to change direction, the applied force (represented as a Vector) must change DIRECTION. A change in magnitude of the Force is not necessary.
Describe a situation in which an object accelerates without changing speed?
Acceleration is the rate of change of velocity over time, so velocity must always be changing if the object is accelerating. HOWEVER, you said speed which means only magnitude, not direction. If you stay the same speed, but change direction then you are accelerating. Simple answer: when you are going the same speed in a circle - velocity changes, therefore acceleration changes.

What changes direction when it meets a continent?
We know that ocean currents change direction when meeting a continent. The water must flow around the land, so it has to change direction to do that.
What actions are required of power boat a when approaching starboard side of the sail boat?
The overtaking vessel must always give way. Therefore the powerboat must be prepared to stop or change direction - the sailboat has right of way.
What must be applied to a objects in order change the objects motion or direction?
A Force.
What must be true about the forces acting on an object if the motion of the object is static?
The forces must be greater in one direction than in the opposing direction, and therefore, must be sufficient to overcome inertia, friction, and any other force that opposes a change in speed.
Why is an electric field strength a vector quantity?
for a vector quantity it must have both magnitude and direction and since it has both magnitude and direction it is therefore considered a vector
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
What must change when a body is accelerating?
A moving body can be accelerated by applying a force. This force will act to increase velocity, decrease velocity or change the direction the body is moving. All three of these are acceleration.
