Question

Explain the following type of motions with one example each
1. positive acceleration
2. Negative acceleration
3. Zero acceleration

Answer 1

POSITIVE ACCELERATION Its there when an object is traveling in the direction of Force applied

NEGATIVE ACCELERATION Its there when an object is traveling in the opposite direction of Force is applied

ZERO ACCELERATION Its the when an object is stationary an motion is not there

Answer 2

Answer:

1) When there is positive acceleration that means the object is moving or experiencing the free fall into the gravitational field.

example:

• If an object is speeding up and moving in a high-quality course, it has a high-quality acceleration. The vehicle speeding up withinside the first instance changed into an instance of high-quality acceleration. The vehicle is shifting ahead in a high-quality course and speeding up, so the acceleration is withinside the equal direction as the car's motion.

2) When there is negative acceleration that means the object is projected vertically upward against the direction of the gravitational field.

negative acceleration way that the charge of the alternate pace is negative or the velocity decreases.

Example:

• When we observe brakes in a moving car, then negative acceleration acts on it and the car stops.
• When we throw a ball upwards, then additional negative acceleration acts on it. Thus, while the ball reaches the highest point, the speed of the ball becomes zero.

3) When then there is zero acceleration that means the acceleration is near the earth's surface. also called uniform motion.

• an object in space that doesn't experience the gravitation force and subsequently floats withinside the area.
