What is required to accelerate an object?
An external force. Force = mass x acceleration
What is the definition of resistance to acceleration?
Inertia resists acceleration. Inertia resists a change in the state of motion of a particle or rigid body. For instance, in order for the state of motion of an object to change, there must be a net external force exerting on the object, which is defined as mass times acceleration. Resistance to this net external force would therefore have to resist the object's acceleration, and that is inertia.
How did changing the slope of the inclined plane change your velocity and acceleration values?
If no other external forces act (apart from weight), the acceleration on a fixed slope remains constant. This is because acceleration is given by: a=gsino where g is the acceleration of free fall and o is the angle between the slope and the horizontal.
When does zero acceleration occur?
Zero acceleration occurs when a body's velocity is constant. Newton's First Law of Motion tells us that this occurs when the external forces acting upon a body are balanced.
If a body is rotating is it necessarily being acted upon by an external torque?
No. Torque is required only for producing angular acceleration. A body rotates with constant angular velocity if no external torque acts on it.
What are The differences between a turbofan and a propeller?
A propeller is completely external and is the main source of propulsion for a airplane with a piston or turbojet engine. A turbofan is more enclosed and provides some propulsion along with also cooling the jet engine that is the main source of propulsion.
What is the difference between a propeller and impeller?
Propeller is external (outboard motor on a boat) Impeller is internal (vehicle water pump).
How does a paper airplane apply Newton's 3 laws?
First law: The speed of the paper airplane remains constant unless acted upon by an external force. At launch, until thrown by someone, the airplane is at rest. In the air, drag (friction) is slowing the aircraft down.Second law: The airplane's acceleration at every instant is equal to the sum of all the forces on it divided by its mass.Third law: As the paper airplane's wings generate lift, they are subject to gravity. When thrown, the airplane has thrust, but drag is also generated.

Resistance to this net external force would therefore have to resist the object's acceleration, and that is inertia.
Is a body in motion also in equillibrium?
Possibly. If there are no external forces acting upon it, and hence no acceleration, then yes, the body can be in equilibrium. But if there is no acceleration,would the body be in motion?
What adding external protrusions to a wing?
increase drag and the amount of thrust needed to move the airplane

The US Coast Guard considers personal watercraft to be?
According to the US Coast guard, a personal watercraft is not powered by an external propeller. The personal craft has its on water jet pump.
If a body is rotating is it necessarily being acted upon by an external torque?
No. Torque is required only for producing angular acceleration. A body rotates with constant angular velocity if no external torque acts on it.
How can acceleration be produced in a body without applying any external force?
Answer #1:It can't.======================Answer #2:By casting off mass.
