What is the meaning of tension force? Give examples. How can you use Newton's second law to find force? What force is needed to maintain the speed of an object if there is no resistance? What is an example of gravitational force?
To find the average friction force when a person has a usual 1 km walk, we can follow these steps:Step 1: Understand the Motion When a person walks, they start from rest and eventually come to a stop. This means that the initia

2) Force is the capacity to do work or cause physical change 3) Force= Mass times acceleration (F = ma) 4) A force is that which changes or tends to change the state of rest or motion of a body. Examples: For simplicity sake, all forces (interactions) between objects can be placed...
What is the friction forceA 25 kg wooden crate is being pushed against a large spring with a spring constant of 1200 N/m. If the coefficient of friction between the crate and the ground is 0.68, how much does the spring have to be compressed to balance out with the friction force...
1. Frictional Force Frictionis one of the vital forces in the world of motion. Even in our daily life activities, we witness it. Represented as –‘Ffrict’. Examples: Motion of wheels on the road of a car while driving. Movement of pen nip against the paper while writing. ...
In physics, a force is any influence that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. 1 Strength Physical power and energy. He showcased...
Force is an influence that can change the motion of an object; load is the weight carried or supported by something.
