Your car has a dead battery. It is initially at rest, and you push it along a level road with a force of 104 N and find that it reaches a velocity of 16.8 m/s in 61 s. What is the mass of the car? Ignore friction. Suppose a car travels at a constant speed ...
So, the force acting on an object (due to contact with another object) is actually a resultant force (based on pressure times area), which is commonly represented as a vector in the equations of motion. This is done for mathematical convenience. ...

if we get tiny pieces of paper close to the comb, it attracts the pieces like a magnet attracting iron fillings. this is because the electrons on the comb attract the positive charge on the paper. this is the force of charges in action. how to calculate the magnitude of the force betwe...

Finally, contractile forces, generated largely by the action of the acto-myosin network, pull the cell forward. After sensing the signal, the cell starts moving in response to the signal by polymerizing actin. If the signal is a chemoattractant, for example, actin polymerizes in the region ...

Get hold of the MCQs on the equilibrium of forces and prepare more efficiently for NEET 2023. Practising these questions will help you get an in-depth understanding of the concepts discussed in the chapter.
The third stumbling block contains questions whereby the student has to recognize the line of action of the appropriate force and take note of the point of application of the force.doi:10.1080/0020739980290405Rowlands, StuartGraham, TedBerry, John...
