Could you sense the difference between uniform motion and rest?

Uniform linear motion: The motion of a particle along a straight line is called its linear motion. When the particle moves with uniform velocity, then no net acceleration is there. When the particle is rest, then also, no net acceleration is present.

How can you differentiate between uniform motion and accelerated motions?

In Uniform Velocity Motion a body will be moving with a constant /unchanging velocity moving in a particular direction and thus acceleration will be zero whereas in Uniform accelerated motion a body will move at constant acceleration and its velocity will keep changing with time at a constant/ steady rate.

Is it possible for a person with a 70 year lifespan travel farther than light travels in 70 years?

Yes, it is possible for a person with a 70-year life span to travel farther than light travels in 70 years (70 light-years). Since time for the moving person slows down, a person traveling at speeds near the speed of light to travel several times farther than 70 light-years during their lifetime.

Can a body be accelerated in uniform motion?

(i) A body can have acceleration even when it has uniform speed. A body in uniform circular motion has uniform speed but at every point its direction of velocity changes, so its motion is accelerated.

Is acceleration a non uniform motion?

Non-Uniform Acceleration: We can define non-uniform acceleration as the acceleration in which the velocity of a body does not change at a constant rate in a given interval of time. In non-uniform motion, the direction of the body or the magnitude of acceleration can change with time. Acceleration is a vector quantity.

Can you get younger by traveling at the speed of light?

We do not age slower if we go at the speed of light but the time stops when we go at the speed of light. The reality is a object having a definite mass cannot achieve speed of light because mass is dependent on speed and when the object reaches near the speed of light we need infinite force to keep it accelerating.

Can an astronaut travel more slowly than the speed of light and yet travel the same distance in a 10 year trip?

Explain. An astronaut traveling with a speed less than the speed of light can travel farther than 10,000 light years in 10 years measured by her. Consider a high-speed spaceship equipped with a flashing light source.

Can a body have uniform speed and non uniform acceleration?

If the velocity of an object changes (i.e. velocity is non- uniform) in each unit of time is constant, then the object is said to be moving with uniform acceleration. So, a body can have uniform acceleration with non uniform velocity.

How can a body moving with uniform speed can causes acceleration?

The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.

What is the differences between uniform acceleration and non uniform acceleration?

Uniform Acceleration: We can define uniform acceleration as the acceleration in which the velocity of a body changes at a constant rate in a given interval of time. In non-uniform motion, the direction of the body or the magnitude of acceleration can change with time.

What is the difference between uniform acceleration and non uniform acceleration with example?

Uniform acceleration is the change of equal velocity in equal interval of time. Non uniform acceleration is the change of unequal velocity in equal interval of time. The motion of a ball rolling down. A car travels 2 km in 1st hour and 2.5 km in 2nd hour.
