Can the velocity of object reverse direction when its acceleration is constant?
Yes, the velocity of an object can reverse direction even when its acceleration is constant. This can happen when the object is subjected to an acceleration in the opposite direction to its initial velocity, causing it to slow down and eventually reverse direction.
When is the acceleration of a body is positive?
A body's acceleration is positive when its velocity is increasing over time. This can happen when the body is speeding up in the same direction as its velocity, or when it is slowing down in the opposite direction of its velocity. Both scenarios result in a positive acceleration value.
Can a direction of velocity of an object reverse at constant acceleration?
Yes, the direction of an object's velocity can reverse even when it is experiencing constant acceleration. This can happen if the acceleration is in the opposite direction to the object's initial velocity.
Can two directions of velocity of an object change when acceleration is constant?
An object can have only one velocity at any point in time. That velocity can have components in two (or more) directions.If acceleration is constant (but non-zero), then the velocity in any direction other than perpendicular to the direction of the acceleration must change.
Can direction of velocity of a body change when its acceleration is constant?
Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.
Can the velocity of object reverse direction when its acceleration is constant?
Yes, the velocity of an object can reverse direction even when its acceleration is constant. This can happen when the object is subjected to an acceleration in the opposite direction to its initial velocity, causing it to slow down and eventually reverse direction.
When velocity is negative and acceleration is zero what happen the object in the motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
When is the acceleration of a body is positive?
A body's acceleration is positive when its velocity is increasing over time. This can happen when the body is speeding up in the same direction as its velocity, or when it is slowing down in the opposite direction of its velocity. Both scenarios result in a positive acceleration value.
Can a direction of velocity of an object reverse at constant acceleration?
Yes, the direction of an object's velocity can reverse even when it is experiencing constant acceleration. This can happen if the acceleration is in the opposite direction to the object's initial velocity.

What happens to an object's motion when 2 equal forces act on an object in opposite directions?
Nothing! If the two forces are equal and opposite then they will cancel each other out. What will happen next is described in Newton's First law when it says "An object in motion will stay in motion unless acted upon by an outside force". Two equal and opposite forces have the same effect as no force, therefore the object's motion will remain the same as if it had never been acted upon by the two opposite forces.
Can direction of velocity of a body change when its acceleration is constant?
Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.
Why is the velocity of accelerated body may be zero?
The velocity of an accelerated body may be zero when it temporarily stops moving at a specific point during its acceleration process. This can happen if the body changes direction or experiences a deceleration that causes its velocity to drop to zero before changing again to increase its velocity in the opposite direction.
What must happen for acceleration to occur?
For acceleration to occur, there must be a change in an object's velocity over time. This change can happen by increasing or decreasing the object's speed or by changing its direction of motion. In essence, acceleration is a measure of how much an object's velocity changes per unit of time.
What happen when opposite forces acting on an object are balanced?
Assuming this is a physics question, when all the forces acting on an object are balanced, the object is in equilibrium. For example, when a car is at a constant velocity, with no acceleration, all the forces are equal.
How does acceleration occur?
Acceleration occurs when there is a change in an object's velocity, either in its speed, direction, or both. This can happen due to forces acting on the object, such as gravity, friction, or propulsion. The rate of change in velocity over time determines the magnitude of the acceleration.
