What is the measure of intertia in an object?
Inertia is the tendency of an object to remain still, or remain moving at a constant speed in a straight line, unless acted upon by an outside force. Thus the measure of this quality is the mass of an object since acceleration is equal to the force applied to an object multiplied by its mass. The greater the mass, the less acceleration a given force will impart to it. In order to impart greater acceleration to a given mass, greater force is needed.
Why contact force between surface increases when speed increases?
As the speed increases, the force of contact between the surface and the object increases because the object has more momentum and exerts a greater impact force on the surface. This is due to a combination of factors such as momentum transfer, friction, and surface deformation, leading to an increase in the contact force.
Is friction a greater force when motion is faster?
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.
How do you calculate force if you only have speed?
To calculate force when given speed, you would need to know the mass of the object. The equation that relates force, speed, and mass is F = m*a, where F is the force, m is the mass, and a is the acceleration (change in speed over time). Without knowing the mass or acceleration, it is not possible to calculate the force.
How is friction increased in a given system?
Friction in a system can be increased by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or by increasing the speed at which the surfaces move against each other.
How do you compute the force of a given mass at a constant speed?
The force on a mass moving at a constant speed and direction is 0.

Is the force the speed?
Force is not speed. Force is what makes an object change its speed. In other words force produces acceleration, which changes speed. The exact relation is given by one of Newton's laws of motion f=ma you can rewrite this as acceleration= force / mass
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
Why contact force between surface increases when speed increases?
As the speed increases, the force of contact between the surface and the object increases because the object has more momentum and exerts a greater impact force on the surface. This is due to a combination of factors such as momentum transfer, friction, and surface deformation, leading to an increase in the contact force.
Is friction a greater force when motion is faster?
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.
What are factors that can affect speed?
Thrust and friction in the environment. Ignoring friction, the two chief factors are the force of acceleration and mass, which determines how much force is required to achieve a given speed (more technically the change of velocity: speed in a given direction).
How do you calculate force if you only have speed?
To calculate force when given speed, you would need to know the mass of the object. The equation that relates force, speed, and mass is F = m*a, where F is the force, m is the mass, and a is the acceleration (change in speed over time). Without knowing the mass or acceleration, it is not possible to calculate the force.
How do you find force when given a constant speed and force of friction?
If the speed is constant, then the group of forces acting on the object is balanced. So the portion of the force acting in the direction of the motion must be equal and opposite to the force of friction.
How is friction increased in a given system?
Friction in a system can be increased by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or by increasing the speed at which the surfaces move against each other.
How does force affect speed of an object?
Force can increase or decrease the speed of an object. If a force is applied in the direction of motion, the object will accelerate and its speed will increase. On the other hand, if a force acts in the opposite direction of motion, the object will decelerate and its speed will decrease.
How do you find mass if you are given velocity force and speed?
force=mass x acceleration. you have force lets say 100N. you are given a velocity of lets say 10m/s at the first second. and you are given speed. if you are given one speed, then you are given the change in velocity (your acceleration). if you are given multiple speeds, then you can figure out your change in velocity of the amount of time the speeds are given as (also your acceleration). So lets say you are given a speed of 30m/s at the third second (second second sounds redundant). Assuming acceleration is constant as always, 30-10=20m/s over 2 seconds. So 20/2=10m/s2. now you have force and acceleration. 100= m x 10m/s2. m=10kg.
