Why do heavy objects have greater forces when being dropped?
The formula for forces reads "F=m*a" The acceleration is constant at 9.8 meters/second on earth. Therefore, in order for the equation to balance, if the mass is increased, the force also increases proportional to the mass.
What does it mean to sat that the net force determines an objects acceleration?
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.
In a vacuum does an object have buoyant force?
No, an object in a vacuum does not experience buoyant force because there is no surrounding fluid to displace or exert an upward force on the object. Buoyant force is a phenomenon that occurs in fluids, such as air or water, and is responsible for objects floating or sinking.
When two objects of different mass are dropped from the same height doesn't it contract Newton's 2nd Law?
No, dropping two objects of different mass from the same height doesn't contradict Newton's 2nd Law. The law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, so objects of different mass will experience different accelerations due to gravity even when dropped from the same height.
Does an object at rest have forces acting on it and if so what forces would be along the vertical axis?
Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.
Are objects in vacuum heavier than air?
No, objects have the same weight in a vacuum as they do in air. Weight is a measure of the force of gravity acting on an object, which is independent of the surrounding air or lack thereof. However, objects feel lighter in a vacuum because there is no air resistance to oppose their motion.
What happens when a hollow plastic ball and a sollid metal ball is dropped in a vacuum and gravity is the only force?
When a hollow plastic ball and a solid metal ball is a dropped in a vacuum and gravity is the only force acting on the balls the balls will fall at the same rate. Being that this is a prediction answer may vary.
How do objects in free fall in a vacuum accelerate?
Objects in free fall in a vacuum accelerate due to the force of gravity acting on them. In the absence of air resistance or other external forces, the only force acting on the object is gravity, causing it to accelerate at a constant rate of 9.8 m/s^2 towards the Earth's center.
What word is An object that has an unbalanced force acting on it will accelerate in the direction of that force?
A Vacuum.
How do you find the net force of two objects acting in the same direction?
To find the net force of two objects acting in the same direction, simply add the individual forces together. The net force will be the sum of the individual forces acting on the objects.
What is the Force acting at a distance between two objects?
The force acting at a distance between two objects is known as the gravitational force. This force is responsible for the attraction between objects with mass and is described by Newton's law of universal gravitation.
What is the relationship between the mass of an object and its rate of fall in a vacuum?
In a vacuum, all objects fall at the same rate regardless of their mass. This is because in the absence of air resistance, the only force acting on the object is gravity, which causes all objects to accelerate at the same rate due to the gravitational force pulling them downward.
Why do objects accelerate on ramps?
Objects will accelerate if there is a net force acting on them.
How much does an object weigh in air?
An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.
Can objects be weightless?
Yes. An object is weightless if gravity is the only force acting on it. (for example, a ball falling in a vacuum) There is no true "weightlessness", because, even if two masses are separated by billions of light years, there is still a gravitational attraction force. There is a distance at which this cannot be felt anymore, but there is still a force.
What is a force acting between two objects?
gravity
Is 20kg lead in a vacuum heavier than 20kg feather in a vacuum?
No. Weight = mass x gravity, so for the same mass, you get the same weight.
