What is the rate at which speed or direction changes?
Acceleration
All objects resist changes in?
acceleration.
Acceleration is defined as the rate change of position true or false?
Acceleration (ack-sell-uh-RAY-shun) is can be absolute, angular, and coriolis. All three are accelerations because they change position/speed over time. Velocity is a measure of distance moved over time. Acceleration is velocity that is changing (speeding up or slowing down, or changing direction) Absolute: The speed continually changes. (A car speeding up) Angular: The direction continually changes. (A planet circling the Sun in orbit) Coriolis: A combination of the above, where a particle changes its distance (absolute) to the center of a whirling mass (Angular).
What is the value of acceleration for a body?
Acceleration means how fast the body's velocity changes - in symbols, dv/dt. Average acceleration during a certain time is equal to (change in velocity) / (time elapsed). Since you are dividing a velocity by a time, the standard unit for acceleration is (meters / second) / second, but this is normally written as meters / second squared.
What is the rate at which velocity changes over time called?
Acceleration. Not buttery in the slightest.
Which of the velocity component of projectile changes and other remain constant why?
The vertical velocity component changes due to the effect of gravity, which causes acceleration in the downward direction. The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming air resistance is negligible).
What does a projectile motion graph illustrate about the motion of an object?
A projectile motion graph illustrates the path of an object in motion, showing how its position changes over time. It typically shows the object's vertical and horizontal displacement, velocity, and acceleration as it moves through the air.
What is the trajectory of the projectile?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
What is the shape of a projectile trajectory?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
The vertical component of velocity changes due to the influence of gravity, which accelerates the projectile downwards as it moves. The horizontal component of velocity remains constant because there is no horizontal force acting on the projectile, assuming air resistance is negligible.
What are two velocity components of projectile motion?
The two velocity components of projectile motion are the horizontal component and the vertical component. The horizontal component remains constant throughout the motion, while the vertical component changes due to the acceleration of gravity.
What type of Motion is the Horizontal motion of a projectile?
The horizontal motion of a projectile is typically considered as uniform motion, meaning the object moves at a constant velocity without any acceleration in the horizontal direction. This motion is not affected by gravity and only changes due to external forces like air resistance.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
What does the acceleration vs position graph reveal about the motion of an object?
The acceleration vs position graph shows how the object's acceleration changes as its position changes. It can reveal information about the object's speed, direction, and changes in velocity.
Projectile's vertical velocity component changes at a constant?
The vertical velocity component of a projectile changes at a constant rate due to the acceleration of gravity. This acceleration causes the projectile to speed up as it moves downward and slow down as it moves upward. The magnitude of the acceleration is constant near the Earth's surface, at approximately 9.8 m/s^2.
Which is a characteristic of projectile motion?
One characteristic of projectile motion is that the object follows a curved path under the influence of gravity. This motion can be divided into horizontal and vertical components that are independent of each other. The object’s velocity changes due to the constant acceleration from gravity.
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
