Force and Laws of Motion

What is Newton's First Law of Motion?

• An object will move in a circular path when no force is acting on it

• An object will stop moving when no force is acting on it

• An object will accelerate when no force is acting on it

• An object will remain at rest or in uniform motion unless acted upon by an external force.

State Newton's Second Law of Motion.

• The force acting on an object is equal to the velocity of that object multiplied by its mass.

• The force acting on an object is equal to the mass of that object divided by its acceleration.

• The force acting on an object is equal to the mass of that object multiplied by its acceleration.

• The force acting on an object is equal to the distance traveled by that object divided by its time.

Explain the concept of Inertia as per Newton's First Law.

• Inertia is the tendency of an object to change its state of motion easily

• Inertia is the tendency of an object to attract other objects

• Inertia is the tendency of an object to resist changes in its state of motion.

• Inertia is the tendency of an object to move at a constant speed

How is force related to acceleration according to Newton's Second Law?

• Force is equal to acceleration

• Force has no effect on acceleration

• Force is inversely proportional to acceleration

• Force is directly proportional to acceleration

Give an example of Newton's Third Law of Motion.

• When a person walks, the ground moves in the opposite direction.

• When a person sits in a chair, the chair moves in the opposite direction.

• When a person claps, the air moves in the opposite direction.

• When a person jumps off a boat, the boat moves in the opposite direction.
