Question

1. Two cars are moving at the same velocity. Car A has a mass of 95 kilograms while car B has a mass of 110 kilograms. How much inertia does the car B have compared to car A?

A. The inertia of the car B is twice as the inertia of car A.
B. Car B has greater inertia than car A.
C.Car B has less inertia than car A.
D. Both have the same inertia.


2. Which of the following statements best describes the first law of motion?
A. A moving object that is not acted by an external force will decelerate
B. A moving object that is not acted by an external force will remain at rest.
C. A moving object that is not acted by an external force will remain in motion
D. A moving object that is not acted by an external force will eventually come to a stop. 16

3.Which of the following is true about inertia?
A.Inertia is an example of force.
B.Inertia can make the object in motion.
C.The massive the object is,the greatethe inertia.
D.The smaller the object is the greater the inertia.

4.Which of the following is NOT a cause of a net force?
A.An object at rest will start moving.
B.An object in motion will eventually stop.
C.There is a change in direction of a moving object.
D.An object will continuously move at a constant velocity.

5.What is the natural tendency of an object to remain in a state of rest or remain in uniform motion in a straight line?
A.Acceleration
B.Inertia
C.Interaction
D.Velocity​

Answer 1

Answer:

1. B

2. C

3. C

4. D

5. C

Explanation:

1. inertia is the measure of mass.

2. According to Newton's first law of motion, if a body is in the state of the rest, it will remain in the state of rest and if it is in the state of motion, it will remain moving in the same direction with the same speed unless an external force is applied on it.

3.it is bcz the greater the mass, the greater is the inertia of a body.

4. Newton's first law of motion.

5. Inertia is the inherent property of each object.
