Question

Differentiate between:
1. Frictional force and gravitational force
2. Force and thrust
3. Electrostatic force and muscular force
4. Sliding friction and rolling friction
pls tell the ans fast..
give 3 for each pls​

Answer 1

REQUIRED ANSWER$ ✍️:-

1. FRICTIONAL FORCE:

• The force of friction is created between two rough surfaces.
• The frictional force always acts against the direction of motion.
• EXP- Walking on the road.

GRAVITATIONAL FORCE:

• Gravitational force is created by the earth's surface and it acts on every object present on the earth.
• The motion of an object goes increasing with an increase in gravitational force.
• EXP- An apple falling from a tree.

2. FORCE:

• Force is a push or pull on an object that produces acceleration in the body on which it acts.
• Force can change the direction of motion of a body.
• EXP- The force of a bat on the ball.

THRUST:

• The force that acts on an object perpendicular to its surface is called thrust.
• Thrust is generated most often through the reaction of accelerating a mass of gas.
• EXP- A fish being expelled from the ocean by a strong wave.

3. ELECTROSTATIC FORCE:

• Electrostatic force can be stated as the force between two electrically charged particles.
• They can either be a repulsive or attractive force. It is non-contract force.
• EXP- Balloons get attracted to another balloon when one of them are rubbed with hair.

MUSCULAR FORCE:

• Force which is exerted by muscles of the body is called muscular force.
• They are neither repulsive nor attractive. It is a contact force.
• EXP- Carrying a bag on your shoulders.

4. SLIDING FRICTION:

• When the surface of one body is sliding against the surface of another body, sliding friction comes into play.
• Sliding friction occurs due to interlocking between microscopic bumps on surfaces.
• EXP- The frame and the edge of the door sliding against one another.

ROLLING FRICTION:

• When the surface of one body is rolling against the surface of another body, rolling friction comes into play.
• Rolling friction occurs due to deformation of surfaces.
• EXP- Rolling of ball or wheel on the ground.
