What else can I help you with?
What makes an object move faster and faster when it falls?
An object falls faster and faster due to the acceleration of gravity. As the object falls, it gains speed because the gravitational force pulling it downwards remains constant, causing the object to accelerate until it eventually reaches its terminal velocity.
What is the explosive sound heard when a shock wave from an object traveling faster than the speed of sound reaches the ears of a person?
A sonic boom
What An object is free fall undergoes an increase in?
The speed of an object in free fall increases due to the acceleration of gravity, which causes the object to fall faster and faster until it reaches terminal velocity, at which point the force of air resistance balances the force of gravity.
What will happen if object falls from great height through air of uniform density?
It will fall faster and faster for a while - until it eventually reaches a "terminal speed", at which air resistance and gravity are in balance. After that, it will continue falling at a constant speed.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
If you were travelling faster than light could you still see an object in front of you?
You cannot travel at the speed of light. Period.
Why is it not possible to use sonar to determine the speed of an object travelling faster than the speed of sound?
Sonar uses sound waves to measure distances by calculating the time it takes for the sound waves to bounce back. However, when an object is traveling faster than the speed of sound, the sound waves emitted by the sonar system cannot catch up with the object to bounce back, making it impossible to accurately determine the speed of the object using sonar.
What is the relationship between gravity an speed?
Gravity affects the speed at which objects fall towards the Earth's surface. The greater the gravitational force, the faster an object will accelerate towards the ground. However, once an object reaches terminal velocity, the force of gravity is balanced by air resistance, and the object will fall at a constant speed.
What does 'top speed' mean?
'Top speed' refers to the maximum speed that a vehicle or object can achieve under optimal conditions. It represents the highest rate of travel that can be reached by a particular vehicle or object.
Can an accelerating object have zero speed?
No, an accelerating object cannot have zero speed. Acceleration is the rate at which the speed of an object changes over time. If an object is accelerating, its speed is increasing or decreasing, but it cannot be zero.
Can information travel faster than the speed of light?
No, according to the theory of relativity in physics, information cannot travel faster than the speed of light in a vacuum. This is because as an object with mass accelerates towards the speed of light, its energy increases towards infinity, making it impossible to exceed the speed of light.
The speed an object reaches when the force of gravity is balanced by the force of air resistance?
Terminal velocity is the speed an object reaches when the force of gravity is balanced by the force of air resistance. At terminal velocity, the object no longer accelerates and falls at a constant speed. This speed varies depending on the mass, size, and shape of the object.
