Can the velocity of an object be zero at the same instant its acceleration is not zero?
Consider the gravitational pull of the earth and acceleration due to gravity. When you throw a ball in the air, at the highest point, it is stopped and has a velocity of 0. However, if the acceleration of the ball was also 0, then the ball would not be able to come back down to the earth. In order for the ball to come back down, there must be an acceleration. This acceleration is the acceleration due to gravity which is constant at the surface of the earth at 9.8 m/s^2. Another example: Say a car is rolling down a hill backwards. In order to stop the car from rolling more, the driver accelerates. After a certain amount of time, the car will stop (with velocity of 0) and then it will start moving up the hill again. When it is stopped, the car is still accelerating in order to overcome the force of gravity pulling the car down the hill.
Technically, an object is accelerating if it's changing it's velocity. This includes speeding up, slowing down, and turning. So, yeah, if an object isn't moving at all, but is turning, it's still accelerrating.
What else can I help you with?
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position, while acceleration is the rate of change of an object's velocity.
Is acceleration the same as velocity?
No, acceleration is not the same as velocity. Velocity is the rate of change of an object's position, while acceleration is the rate of change of an object's velocity. Velocity tells us how fast an object is moving and in what direction, while acceleration tells us how quickly an object's velocity is changing.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration measures how quickly an object's velocity is changing.
How can acceleration affect velocity?
Acceleration is the rate at which velocity changes. If an object experiences acceleration in the same direction as its velocity, its speed will increase. If acceleration is in the opposite direction of velocity, the object will slow down. Changes in acceleration can also affect the direction of velocity, causing the object to change direction.
What has a velocity and acceleration vector in the same direction?
An object with a constant acceleration and velocity in the same direction will have both vectors pointing in the same direction. This occurs when an object is moving in a straight line with a constant speed while its velocity is also increasing at a constant rate.
Can the velocity of an object be 0 at the same instant its acceleration isn't 0?
Yes it can.
Can velocity of an object be zero at the same instant its acceleration is not zero?
Yes. For example a swinging pendulum has zero velocity at the turning point but acceleration is not zero.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position, while acceleration is the rate of change of an object's velocity.
Is acceleration the same as velocity?
No, acceleration is not the same as velocity. Velocity is the rate of change of an object's position, while acceleration is the rate of change of an object's velocity. Velocity tells us how fast an object is moving and in what direction, while acceleration tells us how quickly an object's velocity is changing.
When the acceleration of an object is zero what is the velocity at the same time?
As long as acceleration is zero, the object's velocity is constant.
Is velocity the same as acceleration?
No, velocity and acceleration are not the same. Velocity is the rate of change of an object's position with respect to time, while acceleration is the rate of change of an object's velocity with respect to time. In other words, acceleration measures how quickly an object's velocity is changing.
How can acceleration affect velocity?
Acceleration is the rate at which velocity changes. If an object experiences acceleration in the same direction as its velocity, its speed will increase. If acceleration is in the opposite direction of velocity, the object will slow down. Changes in acceleration can also affect the direction of velocity, causing the object to change direction.
What has a velocity and acceleration vector in the same direction?
An object with a constant acceleration and velocity in the same direction will have both vectors pointing in the same direction. This occurs when an object is moving in a straight line with a constant speed while its velocity is also increasing at a constant rate.
Do acceleration and momentum mean the same thing?
No, acceleration and momentum are not the same. Acceleration refers to the rate of change of an object's velocity, while momentum is the product of an object's mass and velocity. Acceleration measures how quickly an object's velocity is changing, while momentum is a property that depends on both an object's mass and how fast it is moving.
Can an object have zero velocity at the same time that it has acceleration?
Absolutely. That's exactly the situation of a rubber ball that was tossed straight up, at the instant when it's at the top of its arc. Any object that's not connected to anything else and is rising or falling has constant acceleration ... the acceleration of gravity. If it was originally launched upward, then it eventually runs out of steam, stops, reverses direction, and starts moving down. At that instant during its constant acceleration, its velocity is zero.
How does acceleration affect motion in the same direction?
It will increase the velocity of the the object in which the acceleration is applied.
What moving object speed up in what direct is the acceleration?
The acceleration is the same direction of the velocity
