A particle moving in a straight line may or may not have acceleration. Acceleration is adifferent phenomenon altogether. the rate of change of velocity is acceleration, a particle can move in a straight line with a constant velocity thus having no acceleration & it can also move with increasing or decreasing velocities thereby accelerating or deaccelerating.
Acceleration = Final velocity - Initial velocity / time
If it's moving in a curve or some other non-straight path, then yes. If it's moving in a straight line, then no.
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
A straight slanted slope on a velocity-time graph indicates that the object is moving with a constant acceleration.
It is moving at a constant speed with no acceleration nor decceleration
5. A particle is moving along the x-axis. The line graph shows the velocity of the particle over time. When is the instantaneous acceleration of the particle equal to 0?

If a body is moving at constant velocity in a straight line, the acceleration is zero and the net force acting on it is zero. F = ma F = m x 0 F = 0
The only thing that causes or influences acceleration of an object is force.
Acceleration = Final velocity - Initial velocity / time
If it's moving in a curve or some other non-straight path, then yes. If it's moving in a straight line, then no.
the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
zero
acceleration
"Constant rate" implies there is no acceleration - acceleration is zero.
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
