Question

Answer the following:

1. Differentiate between Uniform acceleration and variable acceleration. Which quantity shows direction of motion.

2. State Newton's third law of motion.

3. What is Inertia?

4. Derive equation of motion using graphical method.

5. Which principle is followed in take off of the rocket?

6. Give example of vector quantity​

Answer 1

Explanation:

newtons third law.- for every action their is equal and opposite reaction

Answer 2

Answer:

1. Uniform acceleration is a type of acceleration where the rate of change of velocity changes in equal intervals of time however small the time interval is. But in the other hand ,Variable acceleration or Non-Uniform acceleration is a type of acceleration where the rate of change of velocity doesn't changes in equal intervals of time however small the time interval is.

2.Newton's Third Law Of Motion states that "To every action ,there is always an equal and opposite reaction."This a means that the action and reaction are same in magnitude but act in opposite directions on different bodies.

3.The tendency of property of an object to resist any chance in its motion or rest is known as it's inertia.Inertia is directly proportional to the body's mass i.e., the greater the mass the greater the inertia.

5.In the case of rocket launching ,Newton's Third Law Of Motion is applied.

6.An example of vector quantity is acceleration,Momentum,Displacement,Velocity etc.
