Which law says an object wants to move in a straight line?
The Law of Inertia states that moving objects go in a straight line.
What does Newton’s first law of motion state?
Newton’s first law: the law of inertia Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.
What motion moves in a straight line?
Rectilinear motion. (a train moving on a track, a parade, coins tossed in the air are all in rectilinear motion.)
What causes an object to move in a straight line?
While the inertia of an object causes it to move in a straight line, a force applied at an angle to the straight-line motion will overcome the object’s inertia. Note: The word “centripetal” implies motion is around a center point, as opposed to simply changing direction.
What is state motion?
The state of motion of an object is defined by its velocity – the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.

Which type of motion of an object that moves in a straight line * 1 point rectilinear motion periodic motion circular motion None of the above?
motion Linear motion
Answer:
| Oscillatory motion | Linear motion |
|---|---|
| The type of motion in which the object moves to and fro repeatedly about a mean or a fixed position is known as oscillatory motion. | The type of motion in which the object moves from one point to another in a straight line is called linear motion. |
What force causes an object to move in a curved or circular path?
Centripetal Force
Sometimes objects move in a curved or circular path. While an object moves due to velocity, or its speed in a certain direction, centripetal force is the force that keeps the object moving in a circular path. It does this by pulling an object toward the center of a circle.
What is the tendency of an object to keep moving in motion?
Inertia is the tendency of an object to resist changes in its state of motion. The state of motion of an object is defined by its velocity – the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity.
What are Newton’s 3 Laws of Motion?
The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction.
What is the first law of motion according to Newton?
Newton’s First Law of Motion Newton’s First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it. Similarly, if the object is at rest, it will remain at rest unless an unbalanced force acts upon it. Newton’s First Law of Motion is also known as the Law of Inertia.
What happens to an object in the state of uniform motion?
An object continues to be under the state of uniform motion unless an external force acts on it. Force is a product of mass and acceleration. For every action, there is an equal and opposite reaction. Newton’s first law of motion is also known as the law of inertia.
How does friction affect the first law of motion?
Newton’s first law of motion states that there must be a cause—which is a net external force—for there to be any change in velocity, either a change in magnitude or direction. An object sliding across a table or floor slows down due to the net force of friction acting on the object.
How does mass affect newton’s second law of motion?
Newton’s Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will need to be to cause it to accelerate. This Law may be written as force = mass x acceleration or:
