Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
Oh, dude, the positive direction on the y-axis is like the upward direction. You know, where things go when they're feeling optimistic and want to reach for the stars. So, if you're looking at a graph and you see things going up, that's the positive y-direction. Easy peasy, right?
1, 2, 7, 14, 49, 98: 1 x 98, 2 x 49, 7 x 14.
The acceleration of a body is positive when the body is speeding up in the direction of its velocity. This occurs when the force applied to the body is in the same direction as its motion, causing it to accelerate positively.
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
The displacement vs. time graph would show a curve that is increasing in a positive direction, meaning that the object is moving forward. The slope of the graph would be positive, indicating that the object is speeding up.
The resultant force of a number of balanced forces acting on a body is zero force. The reason is because any force in one direction is always canceled out by another equal force but in the opposite direction. This is what is meant by balanced forces. For every force in the positive direction, there is also an equal negative force in the negative direction. So the forces all add up to Zero. No net force at all.

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.
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.
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
A charger is hooked to a 98 Monte Carlo battery by attaching the positive lead to the positive battery post and the negative lead to a strong ground. The charger is set to the desired rate and plugged in.
