What two things does velocity tell about an objects motion?
speed and direction
What are two unbalanced forces often change an objects motion?
Gravity & Friction.
What two things can change in velocity do?
motion and the angle
What is the force opposes motion between two objects?
Friction is the force that opposes motion between two objects.
Change in an objects motion?
An object's change in motion can be explained by Newton's laws of motion. Newton's first law of motion is: an object in motion stays in motion until acted upon by an outside force...there are two other laws but this is the most famous one
What occurs when any two objects change position relative to each other?
when two bodies change their positions with time, it's termed as motion and if the motion continues it may begin to have velocity,acceleration etc
Does an unbalanced force change an objects motion?
There's no such thing as "an unbalanced force".If the entire group of two or more forces on an objectis unbalanced, then the object's motion changes.
How can forces make things move stop or change direction?
Friction. Friction is the force that opposes motion when two objects rub against each other.
What factors is the attraction between two objects?
The mass, charge, motion (if they are charged) and distance of separation of the two objects.
What are the two things that change the pull of gravity between two objects?
The pull of gravity is affected by the amount of mass, and by the distance.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
What two things do you need to find an objects velocity?
Change in position and change in time velocity= delta displacement/delta time
