What is a sentence with acceleration?
Here is an example sentence with the word 'acceleration':I could feel the acceleration of the roller coaster as the wind whipped wildly against my hair.
How can you have negative acceleration but not negative speed?
The negative part in negative acceleration is indicating direction, as acceleration is a vector quantity. Speed however, is a scalar and has magnitude only and therefore cannot be negative. An example could be -2.6ms-2 meaning that there is an acceleration of 2.6ms-2 but in the opposite direction to other vectors.
How could you keep an object acceleration the same if the force acting on object were doubled?
force = mass * acceleration if force is doubled, mass needs to be doubled to keep the same acceleration example: force = 6 mass = 2 acceleration = 3 6 = 2 * 3 12 = m * 3 12/3 = m 4 = mass
How does a graph slowing speed differ from a graph showing acceleration?
Yes. One shows speed and the other shows acceleration. The variables are usually plotted against time but that need not be the case. They could be plotted against displacement, for example.
Does negative acceleration have constant acceleration?
Not necessarily so. Negative (deceleration) could be growing or decreasing in magnitude. The cause is going to be the Force that is acting on the system. If the Force is increasing, the acceleration will be also.
What can positive acceleration called?
Positive acceleration could be called "speeding up" if you felt like it.
What are vectors and 1 example?
Vector is magnitude and direction. As opposed to scalar having only direction. Example: Velocity Acceleration Applying this to a question could be observeted as the bus moved 40km/h in a East direction.
What is an example of something that undergoes acceleration while moving at a constant speed?
An object moving in a circle at a constant speed undergoes acceleration because its direction of motion is continuously changing, even though its speed stays constant. This acceleration is called centripetal acceleration and is directed towards the center of the circle.
What could describe the magnitude of a vector?
A vector could describe a something physical like a force or velocity or acceleration or torque for example. The units would be part of the magnitude of the vector. For example, the wind is blowing South at 10 mph. The magnitude is 10 miles per hour.
How do you find the magnitude of acceleration using force and distance?
I don't think that is possible. You need some more information. You can use Newton's Second Law: acceleration = force / mass. Or, you can use one of the formulae for constant acceleration. For example, you might use one that involves initial speed (which could be zero), final speed, and distance.
Which characteristics of motion could change without changing the velocity of an object?
Some characteristics of motion that could change without changing the velocity of an object include acceleration, direction, and position. For example, an object moving in a circle at a constant speed has a changing acceleration (centripetal acceleration), changing direction, but constant velocity. Similarly, an object can change its position while maintaining a constant velocity if it moves along a straight path.
Can the velocity reverse the direction when acceleration is constant?
Yes, it can, if the initial velocity vector of an object was in opposite direction to its constant acceleration. Example: Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
