Which of the following refers to the tendency of an object to maintain its state of rest or of uniform velocity in a straight line?
law of inertia, also called Newton's first law, postulate in physics 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.
What is the tendency to stay in motion?
1st Law of Motion. (Law of Inertia) An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity, unless acted upon by an unbalanced force. 1st Law of Motion. Inertia is the tendency of an object to resist changes in its velocity: whether in motion or motionless.
Which has more tendency to oppose any change in its state of motion?
Detailed Solution. The correct answer is inertia. CONCEPT: Inertia: It is the property of a body by virtue of which the body resists the change in its initial state of rest or motion with uniform speed on a straight line.
What are the two states of motion?
For a body having a constant speed, the state of motion is uniform motion. For a body having variable speed and (or) direction, the state of motion is non-uniform motion.
Why is apparent motion important?
Apparent motion can impair and enhance target visibility: the role of shape in predicting and postdicting object continuity. Some previous studies have reported that the visibility of a target in the path of an apparent motion sequence is impaired; other studies have reported that it is facilitated.
What is an actual motion in Science?
[′ak·chə·wəl ′mō·shən] (navigation) Motion of a craft relative to the earth.
What is a scene schema?
Scene schema. A person's knowledge about what is likely to be contained in a particular scene. This knowledge can help guide attention to different areas of the scene. For example, knowledge of what is usually in an office may cause a person to look toward the desk to see the computer.
How does the phenomenon of apparent movement work?
…apparent movement (called the visual phi phenomenon) depend on persistence of vision: visual response outlasts a stimulus by a fraction of a second. When the interval between successive flashes of a stationary light is less than this visual-persistence time, the flicker will appear to fuse into a continuous light.

A late traveler rushes to catch a plane, pulling asuitcase with a force directed 30 degrees above the horizontal. Ifthe horizontal component of the force on the suitcase is 60.6 N,what is the force exerted on the handle?
What force is used to push a 90.0 kg box across a floor at a constant speed of 2.00?
A force of 400 N is used to push a 90.0 kg box across a floor at a constant speed of 2.00 m/s. The coefficient of sliding friction is
How long does it take for a 1 kg object to stop?
A 1-kg object moving at 1 m/s comes to stop in 0.5 s. The net force acting on it is
What force does a jumper of weight w exert?
A jumper of weight w presses down on the ground with a force of magnitude F and becomes airborne as a result. The magnitude of the force of the ground exerted on the jumper must have been
Why is the upward acceleration of Earth negligible?
the upward acceleration of Earth is negligible because of its large mass. If a non-zero net force is acting on an object, then the object is definitely. being accelerated. A 1-kg object moving at 1 m/s comes to stop in 0.5 s. The net force acting on it is.
Which object will have a smaller acceleration?
the object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration.
What exerts a force on the sidewalk?
The leaf exerts a force on the sidewalk; the sidewalk exerts a force on the leaf.
Is acceleration proportional to mass?
The acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object.
