Can you go around a curve with constant acceleration? No, because the vector always points to the center of the circle and you are always changing the direction of that vector. Can you go back in time or into the future? is it possible to go back in time and change the past.
Can you round a curve with constant acceleration?
——— (a) Yes. Rounding a curve at constant speed means you are accelerating toward the center of the circle. Even though your speed is constant, your velocity vector is changing, so your acceleration is nonzero. … If you follow a curve, the direction of velocity must change.
Is it possible to go around a curve with zero acceleration?
It is not possible to round a curve with zero acceleration because to change the direction of the velocity vector, acceleration must act on the object. However, with constant acceleration, this can be possible, as it happens in uniform circular motion.
Can you go around a curve with the following accelerations explain zero acceleration constant acceleration?
Yes, it is impossible to go around the curved path with zero acceleration. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.
Is constant acceleration a curve?
Constant acceleration means the velocity graph has a constant slope. If the velocity steadily increases, the position graph must have a steadily increasing slope. Constant acceleration results in a parabolic position graph. Once again, the displacement is the area under the curve of the velocity graph.
Is it possible for a body to undergo acceleration although its speed is constant?
If a body is moving with constant speed in a circle, then yes, that body has acceleration.
When a car speeds up when rounding a curve what happens to its centripetal acceleration?
As a car speeds up when rounding a curve, does the centripetal force on the car also increase? Defend your answer. Yes – increased speed at the same radical distance means greater centripetal force.
Is it possible for a body to move in a curved path without acceleration Why?
No, a body cannot move on a curved path without acceleration because while moving on a curved path, the velocity of the body changes with time.
At what point in the path of a projectile is the speed a minimum?
A projectile fired from the ground follows a parabolic path. The speed of the projectile is minimum at the top of its path.
What is acceleration over time?
Acceleration is the rate at which the velocity of a body changes with time. … Because acceleration is velocity in m/s divided by time in s, we can derive a graph of acceleration from a graph of an object’s speed or position.
What happens to position when acceleration is constant?
Position-Time Graph for a Constant Acceleration When the acceleration of a function is constant, the slope of the velocity function is also constant, i.e. a ( t ) = d d t v = constant .
Why is acceleration constant?
The Meaning of Constant Acceleration This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity. … And an object with a constant velocity is not accelerating.
Can a body have 0 velocity and still be accelerating?
Yes, an object can have zero velocity and still be accelerating simultaneously. … Then the object will start to move in the backward direction.
Can a body move with constant acceleration but with zero velocity?
One example of this is the vertical motion of an object. When the object is thrown upwards and reaches the maximum height, the velocity of the body becomes zero, but it still accelerates with constant acceleration. … Hence, we can say that an object moves with acceleration and constant speed in a uniform circular motion.
Does less mass mean more acceleration?
At that time, you will learn that the acceleration of an object is directly proportional to force and inversely proportional to mass. Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration.
Why is centripetal acceleration not constant?
Even if the speed of the particle is constant, the particle has some acceleration just because the direction of its velocity is continually changing. What’s more, the centripetal acceleration is not a constant acceleration because its direction is continually changing.
