the car could be traveling in a straight line and slowing down (negative acceleration), speeding up (positive acceleration) or maintaining constant speed (zero acceleration).
The car's acceleration is
(its change in speed) / (the time for the change) in the direction of the line.
(1) Anything moving in a circle, (2) anything moving along a curved path.
The cart's acceleration will decrease as its mass increases. This is why you must exert progressively more force on a shopping cart to move it along as items are added to it. If you were to continue to add items to the cart but not change how hard you push it, the cart would eventually become "impossible" to push.
Yes, due to its change in direction of motion.
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?
Since no values are given, the answer must be a general one. A particle in circular motion undergoes centripetalacceleration. Inertial motion is straight line motion. Any change in motion (including direction) requires positive or negative acceleration. In order to move along a circular (or any curved) path, a particle's direction of motion is in a constant state of diversion from straight line inertial motion, so it moves under a contant state of acceleration.
8 km/h. s
10 km per hour per second.
On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).
If you want to have that in meters per second square, convert the speed to meters per second (divide by 3.6 in this case). Then, divide the speed by the time.
(1) Anything moving in a circle, (2) anything moving along a curved path.
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
The cart's acceleration will decrease as its mass increases. This is why you must exert progressively more force on a shopping cart to move it along as items are added to it. If you were to continue to add items to the cart but not change how hard you push it, the cart would eventually become "impossible" to push.

For motion at constant speed along a straight line, the acceleration is zero.
In case of uniform acceleration,the graph will be a straight line with a +ve slope ,if we are taking velocity along Y-axis and time along X-axis.hence it's slope will give u acceleration.
yes
Yes, due to its change in direction of motion.
