How is acceleration dependent on the speed and direction of an object?
The acceleration of the object is dependent upon this velocity change and is in the same direction as this velocity change. Objects moving in circles at a constant speed accelerate towards the center of the circle. The acceleration of an object is often measured using a device known as an accelerometer.
When an object is thrown the thrower pushes the object This causes the object to move in a?
Explanation: Oblique movement occurs when an object is thrown and begins its movement at a certain angle to the horizontal. In this type of throw, the object performs two simultaneous movements, while performing a vertical movement, rising and falling, also moving horizontally.
What happens to air resistance when an object accelerates?
As an object falls, it picks up speed. The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating.
When two objects are near each other how would increasing one object mass affect it?
When two objects are near each other, increasing one object’s mass would cause the gravitational force of the object to increase.
What should be done in order to increase the gravitational force between two objects?
So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.
Why does a skydiver achieve terminal velocity?
As the skydiver gains speed, their weight stays the same but the air resistance increases. Eventually, the skydiver’s weight is balanced by the air resistance. There is no resultant force and the skydiver reaches terminal velocity. When the parachute opens, the air resistance increases.
What is the greatest velocity a falling object reaches?
terminal velocity
What is the force that opposes the movement of an object quizlet?
Friction: A Force That Opposes Motion.
Is a push or pull that one object exerts on another?
Exploring Motion and Forces
| A | B |
|---|---|
| acceleration | the rate of change of velocity. |
| force | A push or pull one body exerts on another body. |
| balanced forces | Forces that are equal in size and opposite in direction. |
| inertia | The tendency of an object to resist any change in its motion. Also known as Newton’s 1st Law. |
Is there work done if an object moves?
Work done on an object along a given direction of motion is equal to the force times the displacement times the cosine of the angle. No work is done along a direction of motion if the force is perpendicular.
