How does the direction of acceleration compare with the direction of the net force that produces it?
Acceleration is proportional to net force.That means that acceleration is equal to (net force) times (something).The 'something' is [ 1 / (the mass of the object being accelerated by the force) ].
What does impending motion mean?
I'm pretty sure it means the motion or movement that is going to happen. So, if you apply force in a direction to a box, the impending motion will be sliding or tipping in the direction of force depending on certain coefficients of friction.
How does force influence motion?
Remember Newton's 2nd Law of Universal Dynamics. Force is directly proportional to the change in momentum(acceleration) . So a given force applied to a mass will change its velocity. Remember velocity is speed ( a scalar quantity) in a given direction. So an object moving at constant speed , but changing its direction ( going round in a circle /ellipse) is accelerating; its velocity is changing.
How does force cause motion?
Force causes motion by exerting a push or pull on an object, which results in the object accelerating in the direction of the force. This acceleration is directly proportional to the force applied, according to Newton's second law of motion (F = ma). Once the force stops acting on the object, it will continue to move at a constant velocity due to its inertia.
Why is frictional force called a perverse force?
Frictional force is sometimes called a "perverse force" because it works opposite to the direction of an object's motion, creating resistance and making it harder for the object to move. This frictional force can be seen as going against the desired motion of the object, hence the term "perverse."

Why is going downstairs negative work?
As you walk down the stairs, you apply a force to keep yourself from falling down the stairs. The force is in the upward direction, but your movement is in the downward direction. If the force is in the opposite direction of motion, work done by the force is negative. Gravitational force, because it pulls down, does positive work.

Is it easier to accelerate an object by pushing or pulling it at an angle or by pushing or pulling it horizontal to the motion?
It is generally easier to accelerate an object by pushing or pulling it in the same direction as its motion (horizontal to the motion) because you are adding force in the same direction as the velocity, increasing the speed. Pushing or pulling at an angle will require some of the force to be used in changing the direction, making it less efficient for acceleration.
Friction always acts in a direction?
Friction always acts in the direction opposite to the the motion of the object.For example, if a bowling ball rolls to the right, friction would act to the left.Without friction, if you threw a ball, it would keep going forever. Friction slows objects down.
What is an inward force necessary for circular motion to occur?
No. There is no outward force exerted in circular motion. Inertia is the reasoning. For example, if your in a car going around a roundabout than you are going one way but the car is going the other hence Inertia is present.
What are the situations in which work is not done?
There are 3 conditions for work. First, there must be force. Second, when you apply a certain amount force to an object, it must move a certain distance. lastly, the force that you applied and the direction of the motion must be parallel. If you applied force tot eh right, then the object must move to the right. When you lift a book and then you walk around, no work is done. The direction of the force of your hand is going upwards while the direction of your motion is either left or right. Therefore the force applied and the distance moved are perpendicular.
How does force affect the motion and speed of an object?
As Newton's laws state, the greater the force, the more an object will accelerate or slow down. The force in the opposite direction of motion is called friction. So if you have a 3Kg block travelling at 2m/s, with a friction of 1m/s you will need at least 5N to keep it going. The more force you apply, the faster the block will travel, so it accelerates. The less force you apply the more it slows down and eventually stops because the friction is greater than the force applied. An object that travels in a uniform direction at a uniform speed (Newtons 1st law) will continue traveling in the same way and in the same direction (inertia) unless acted upon by a resultant force (friction).
