In this act what hints or nuances are given of the gathering forces of opposition to Macbeth?
In which act? If you're going to ask for homework answers, at least ask the whole question.
How is net force on an object determined?
Add the different forces together to find the net force. For example, if you have a force of -5N acting on an object and another force of 8N acting on that object, the net force is 3 N.
What happens when a force act on an object?
When a force acts on a body or a object - 1. makes the object move from rest 2.chage in speed 3.change in direction of motion 4.change in shape 5.OR all of these
When two equal forces act in opposite directions an object they are called?
These two forces are balanced and opposing forces, because of the same magnitude, and opposite direction. For example: A box laying on the ground unmoved has 2 forces acting upon it. These forces would be Fg (Force of gravity; downwards direction), and Fn (Force of Normality; upwards direction). Since the magnitude of Fg = Fn, they are balanced and the box will not move.
What is the net force of an object in equilibrium?
You and I stand on opposite ends of a small car.You are in the back, pushing it forward with a force of 100 pounds. I am in the front, pushing it backward with a force of 100 pounds.I don't know what the "force" on the car is. Is it 200 pounds, 100 each from you and me ? Do we also have to add in the weight of the car ... another 2,000 pounds of gravity pushing it downward ? How about the reaction force of the pavement ... another 2,000 pounds pushing it upward ? I don't know.But I do know the net force on the car ... it's zero. The two horizontal forces on it cancel each other, because they're directed in opposite directions. Same for the vertical forces. Which is why the car doesn't accelerate in any direction ... because the net force in that direction is zero.
What is the unbalanced force on an object when two equal and opposite forces of 3 N act on an object?
When two forces acting on an object are not equal in size, we say that they are unbalanced forces. a stationary object starts to move in the direction of the resultant force. ... a moving object changes speed and/or direction in the direction of the resultant force.
Does a 10lb catapult launch further than a 3lb one?
Usually yes...but it depends on the angle of trajectory, weight and aerodynamics of the thing being catapulted, the length of the "arm" of the catapult, and the amount of force that the catapult is set to hurl the object. Example: a feather on the 10lb catapult which is set at a high trajectory and a low force will go almost nowhere while a stone from a 3 pound catapult will go much farther if it is set on a perfect trajectory and maximum force.
3. Some forces act at a distance and thus do not require .?
Force is split into 2 different "types" contact forces act between 2 objects that are TOUCHING, non-contact forces act as a distance and are not contacting. So the answer would be contact.
Is a catapult a 1 class lever?
no. a catapult is a class-3-lever not a class-1-lever.
How many syllables does catapult have?
3
Newton's law of motion- states that forces always act in equal but opposite pairs?
Yep. But this is Newton's THIRD law of motion. He actually came up with three laws of motion that we use today.1: An object in motion will remain in motion and an object at rest will remain at rest unless acted upon by another force.2: An object acted upon by a force will accelerate in the direction of that force.3: Forces always act in equal but opposite pairs.-(Basic definitions!)-
What are the 3 things forces can do when acting on an object?
Change the Direction, Change the Speed and Change the Shape :)
What are the 2 forces acting on a sinking object?
There are 3 (I am doing physics IGCSE and my paper says state the 3 forces acting on a sinking anchor), but I only know one, upthrust!
When forces act in opposite direction?
When two equal forces act in opposite directions, they are called balanced forces, and no motion takes place. If they are unequal, than the weakest force is cancelled out, along with an equal amount of the strongest force. For example, if an object is being pushed on opposite sides with 7 and 10 newtons of force, then the 7 newton force will be entirely cancelled out, along with 7 newtons of the 10 newton force. This will leave a net force of 3 newtons acting on the object. If there is a net force (also called an unbalanced force), then motion will take place.
When finding net force why must you know the direction of the forces act on an object?
In order to find the Net forces, you need to know the X, Y and Z component of the object since their vectors(unit of distance and direction) are used to calculate the magnitude and direction of the object.... for example, if an object moves 3m in the X-axis and 4m in the Y-axis, then the net distance is 5m with an angel of tan(@)=4/3... Thus we know the distance and direction of the object... This can also be used for velocity (m/s), accelerations(m/s^2), and jerk (m/s^3)... note, that an object will always have a Y component of 9.81m/s^2 (gravity)...
What are the conditions for an object to stay at restto keep moving at constant velocityor to move with increasing velocity?
You have three separate situations here:1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.
How many men did it take to push a catapult?
