What is a peak force?
Peak force refers to the maximum amount of force exerted during a specific period of time, such as in a particular motion or exercise. It represents the highest level of force generated by a muscle or exerted on an object before decreasing.
What two things affect the level of an object acceleration?
The two things that affect the level of an object's acceleration are the magnitude of the applied force and the mass of the object. A greater force exerted on an object or a smaller mass will result in a higher acceleration.
What does force strength mean?
Force strength refers to the level of physical power or capability that an individual or object possesses to exert force on another object or resist external forces. It is often measured in terms of the amount of force that can be exerted or resisted in a specific situation.
Is it true that on a level surface applied forces equals weight?
No, on a level surface, the sum of all applied forces equals zero if the object is not accelerating. Weight is the force exerted by gravity on an object and is equal to the mass of the object multiplied by the acceleration due to gravity.
Why do things have weight?
Things have weight due to the gravitational force exerted by the Earth on them. The weight of an object is the measure of the gravitational force acting on it, pulling it towards the Earth's center. This force is directly proportional to the mass of the object.
When a car speeds up does the drag increase or decrease?
as an object accelerates, the amount of drag exerted on it increases. This means that more force is necessary to sustain the same level of acceleration. If that external force is increasing, as in a car or plane, then the object can be accelerated well past its terminal velocity. If, however, the only force being exerted on it is the force of gravity, then eventually the drag will become as great as the static force of gravity, and the object will cease to accelerate.

Weight is the result of air pressure exerted upon an object?
Weight is the force of gravity acting on an object's mass, not air pressure. Air pressure is the force exerted by the atmosphere on objects. Weight depends on the mass of the object and the acceleration due to gravity, while air pressure depends on the density of air and the height above sea level.
What is the formula for finding the force exerted by an object?
In physics, Force is what changes or tends to change a state of rest or motion in an object. Force causes objects to accelerate, add to the object's overall pressure, or change direction. Force is measured in Newtons (N). According to Newton's Second Law of Motion, the formula for finding force is: : F = ma where F is the force,m is the mass of an object,and a is the acceleration of the object. If one sets a to the standard gravity g, then another formula can be found: : W = mg where W is the weight of an object,m is the mass of an object,and g is the acceleration due to gravity at sea level. It is about 9.8m / s2. Force is a vector, so it has both a magnitude and a direction. Linear force can be found with this formula: F = LD L is the length of the lever arm and D is the distance it has traveled.
Why doest air pressure crush objects such as a desk?
Because that air pressure is the same on all sides and inside objects. If you were to seal a container at the top of Mt. Everest, Then took it down to Sea Level, It might crush (depending on the strength of the container) because the air pressure inside would be much less (the same as at the Peak where you sealed it) then it is at sea level.
What force makes object change positions?
Any force will accelerate an object to change its position. It might be gravitational, electric, magnetic, etc -- even muscle force, which is ultimately electrical at the atomic level. There are many kinds of forces, all of which can accelerate objects that have mass.
Do force exist to object at rest?
There CAN be, as long as the force is being counterd by an equal and opposite force.
What is the force exerted by the atmosphere?
The force exerted by the atmosphere is called atmospheric pressure. At sea level, atmospheric pressure is about 14.7 pounds per square inch (psi) or 101.3 kilopascals (kPa). Atmospheric pressure decreases with increasing altitude.
