Relative motion can best be defined as

• the change in position of an object divided by change in time.

• the amount of motion that an object experiences over a given period of time.

• the motion of an object with a constant velocity.

• the motion of one object as it appears to another object.

Which statement best describes motion?

• rate of change of the velocity of an object with respect to time.

• change in position of an object with respect to its surroundings in a given interval of time

• refers to "how much ground an object has covered" during its entire travel

• location of the object (whether it's a person, a ball, or a particle) at a given moment in time.

In physics, frames of reference are classified by two main types: _____.

• non - inertial and inertial

• scalar and vector

• inertial and non - accelerating

• real and imaginary

TRUE or FALSE

"Non - inertial frame of reference in classical physics possesses the property that in this frame of reference a body with zero net force acting upon it does not accelerate".

• TRUE

• FALSE

TRUE or FALSE

"An inertial frame of reference is a reference frame in which the law of inertia does not hold".

• TRUE

• FALSE
