Can an object have a speed of zero and the acceleration not be zero?
Yes, but only at one instant. For instance, if you throw an object straight up, when it reaches the highest point its instantaneous speed is zero, but of course its speed is changing - thus, acceleration is non-zero.
When an object reaches its termainal speed its acceleration is zero right?
Acceleration is zero when the object's speed and direction stop changing.
A stone is thrown straight up. when it reaches its highest point?
When the stone reaches its highest point, earth's gravity ensures it has to come down.
What is the acceleration due to gravity when a body reaches the ground?
The acceleration is still 9.8 m/s2 but the force applied by gravity is counteracted by the ground.
Is fire an example of potential energy?
Yes, whenever it reaches its highest point in the air
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.

Give example where the velocity of the particle is 0 and acceleration is maximum?
When a pendulum reaches its maximum elongation the velocity is zero and the acceleration is maximum
What is the acceleration due to gravity when a body reaches the ground?
The acceleration is still 9.8 m/s2 but the force applied by gravity is counteracted by the ground.
What is the answer to A track runner begins running from the starting line and reaches a race pace of 4 min per mile in 5 s What is the runner s acceleration?
It is 4.4 feet per second-squared.
When the sun reaches its highest or lowest part in the sky?
Highest is at noon, and the lowest is at dawn and dusk.
What is the highest point a rocket reaches during flight?
Apogee
