What 2 principal factors affect the force of air resistance on a falling object?
The shape of the object and the density of the gas that the object is falling through.
How does force affect a falling object?
force hits the object and it changes it velocity or speed and its state of motion or rest , push or pull.
What is the force on the ground of a 12kg acorn falling from a tree?
The impact force depends upon the height from which it has fallen (IE- its velocity upon impact), and the duration of impact (determined by the elasticity of the collision). However, the object exerts no force upon the ground *while* falling.
What is true regarding speed and force of impact?
The speed at which an object is moving before impact can affect the force of the impact. In general, the higher the speed, the greater the force of impact. However, the mass of the object also plays a significant role in determining the force of impact, as mass affects the object's momentum during the collision.
How do you predict the weight of an object falling eg what is the impact weight of 63 kgs falling 8.9 meters?
The weight of the object (63 kg) will not change as it falls, as weight is a force due to gravity. The impact force on the object can be calculated using the formula F = m * g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.81 m/s^2). So, the impact force on a 63 kg object falling 8.9 meters can be calculated as 63 kg * 9.81 m/s^2.
How does height affect the velocity of a falling body?
A falling object accelerates at a rate of 9.8 m/s2. That means that for every second that it is falling, its velocity increases by 9.8 m/s. The higher that the object is falling from, the longer it will have to speed up, thus the higher its velocity upon impact will be. (This is assuming that it does not reach terminal velocity, the velocity at which an object can no longer accelerate because it is travelling so fast that the drag force (air resistance) is equal to the force of gravity.)
How was the impact force lessened by the use of the hankerchief?
When a hankerchief is used to catch an object falling through the air, it increases the time of impact by providing a cushioning effect. This increased time reduces the peak force experienced upon impact, lowering the overall impact force.
Is One force affecting an object is air pressure which is?
Yes, air pressure is a force that can affect an object. It results from the weight of air pressing down on an object and can impact its movement or behavior.
When equals the force of gravity on a falling object the object reaches terminal velocity.?
When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.
What is the force that is primarily involved with a falling object?
Gravity is the force primarily involved with a falling object. It pulls the object downward towards the center of the Earth.
When an object is falling toward earth what force is pushing up on the object?
When an object is falling toward Earth, the force pushing up on the object is gravity, which is pulling the object downward towards the Earth's center. There is no active force pushing the object up as it falls.
Name at least two factors that determine force of impact?
The speed or velocity of the object before impact and the mass of the object are two important factors that determine the force of impact. The greater the speed or mass of the object, the higher the force of impact will be.
