Friction
Magnetic force
Electrostatic force
Muscular force
Answer is Right!
Answer is Wrong!
The correct answer is A. Friction.
Friction is a force that opposes the relative motion of two objects or materials. It is caused by the interaction of the microscopic surface features of the two materials. When a ball rolls along the ground, the surface of the ball comes into
contact with the surface of the ground. The microscopic surface features of the ball and the ground interlock, and this interlocking causes the ball to slow down.The other options are incorrect.
- Magnetic force is a force that attracts or repels objects that have a magnetic field. The ball does not have a magnetic field, so it is not affected by magnetic force.
- Electrostatic force is a force that attracts or repels objects that have an electric charge. The ball does not have an electric charge, so it is not affected by electrostatic force.
- Muscular force is a force that is generated by the contraction of muscles. The ball is not moving due to muscular force.
