What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
What is the speed of light as it travels through transparent objects?
The speed varies according to the refractive index of the objects.
What is the acceleration of light from a star?
The speed of light is constant in a vacuum and is approximately 299,792 kilometers per second. Light from a star travels at this speed from the star to Earth without acceleration.
What is light's acceleration if its traveling at a constant speed of 300000 km s?
It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
What is study of velocity speed and acceleration called?
The study of velocity, speed, and acceleration is called kinematics. Kinematics is a branch of physics that deals with the motion of objects without considering the forces causing the motion.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
If Light travels in a straight line at a constant speed of 300000 kilometers per second What is the light's acceleration?
Light does not accelerate as it always travels at a constant speed of 300,000 kilometers per second in a straight line, as per the laws of physics. This is because light does not have mass and therefore does not experience acceleration in the same way that objects with mass do.
What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
How do you calculate a objects acceleration?
Acceleration = (change in speed) divided by (time interval)
When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
What is the acceleration of a car that travels in a straight line at a constant speed of 135 kilometers per hour?
If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
What is the speed of light as it travels through transparent objects?
The speed varies according to the refractive index of the objects.
What kind of acceleration travels at a constant speed in a circular motion?
In circular motion, the centripetal acceleration points towards the center of the circle and is responsible for maintaining the object's direction. This acceleration does not change the object's speed, but instead changes its direction, keeping it in circular motion.
What is the acceleration of a car that travels in a straight line at a constant speed of 110 km h?
The acceleration of an object that travels in a constant straight line velocity is zero.
What happens to your speed if you have a negative acceleration do you speed up or slow down?
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
What is the acceleration of an object that travels in a straight line at a constant speed?
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
