name one type of motion where one point on the body can continuously move faster thwn the other point
Answers
Explanation:
An object moving with constant velocity must have a constant speed in a constant direction.
LEARNING OBJECTIVES
Examine the terms for constant velocity and how they apply to acceleration

Key Points
Constant velocity means that the object in motion is moving in a straight line at a constant speed.
This line can be represented algebraically as:
x
=
x
0
+
vt
, where
x
0
represents the position of the object at
t
=
0
, and the slope of the line indicates the object’s speed.
The velocity can be positive or negative, and is indicated by the sign of our slope. This tells us in which direction the object moves.
Key Terms
constant velocity: Motion that does not change in speed nor direction.
Motion with constant velocity is one of the simplest forms of motion. This type of motion occurs when an an object is moving (or sliding) in the presence of little or negligible friction, similar to that of a hockey puck sliding across the ice. To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion to a straight path.
Newton’s second law (
F
=
ma
) suggests that when a force is applied to an object, the object would experience acceleration. If the acceleration is 0, the object shouldn’t have any external forces applied on it. Mathematically, this can be shown as the following:
a
=
dv
dt
=
0
⇒
v
=
const
.
