What is the acceleration of a car moving along a straight line path that increases its speed from 0 to 100 km per hour in 10 seconds?
10 km per hour per second.
What is positive accelerations?
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.
What is the acceleration of a car moving along a straight line path that increases its speed from zero to 100 kilometers per hour in ten seconds?
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.
As the speed of a bicycle moving along a horizontal surface increases from 2 meters per second to 4 meters per second the bicycle's gravitational potential energy?
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
What is the displacement of a car moving along a straight line path that increases its speed from 0 to 100 km per hour in 10 seconds?
Speed when acceleration begins = 0Speed when acceleration ends = 100 km per hourAverage speed during the 10 seconds = 50 km per hourDistance = (average speed) x (time) = (50 km/hr) x (1 hr/3,600 sec) x (10 sec) = 1388/9 meters

10 km per hour per second.
What is positive accelerations?
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.
When an object is turning a corner what direction is the acceleration?
The acceleration of an object turning a corner is directed towards the center of the circle that the object is moving along. This acceleration is called centripetal acceleration and is responsible for changing the direction of the object's velocity, keeping it moving in a curved path.
Can a particle moving with uniform speed along a curved path have acceleration?
Yes, a particle moving with uniform speed along a curved path can have acceleration because acceleration is the rate of change of velocity, which includes changes in direction even if speed remains constant. In this case, the acceleration would be due to the change in velocity direction as the particle moves along the curved path.
What is a variant of the name of the line used to determine the acceleration of a particle moving along a curved surface?

What is the acceleration of a car moving along a straight line path that increases its speed from zero?
The acceleration of the car is equal to the rate of change of its speed over time. When a car goes from zero speed to a higher speed, it experiences positive acceleration in the direction of its motion.
What is the net force acting if an object is moving along a surface with a constant acceleration?
The net force acting on the object is equal to the product of the object's mass and its acceleration. This net force is responsible for maintaining the object's constant acceleration as it moves along the surface.
On a V-t graph how does constant acceleration appear?
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).
What is a acceleration in a circle?
Acceleration in a circle is the change in velocity of an object moving in a circular path. It can be either centripetal acceleration, which points towards the center of the circle and keeps the object on its path, or tangential acceleration, which changes the speed of the object along the circle.
What is the difference between centripetal acceleration and radial acceleration?
Centripetal acceleration is the acceleration directed towards the center of a circular path, while radial acceleration is the acceleration directed along the radius of the circle. In simpler terms, centripetal acceleration keeps an object moving in a circle, while radial acceleration changes the speed of the object.
Is it possible to experience centripetal acceleration but not tangential acceleration?
Yes, it is possible to experience centripetal acceleration without tangential acceleration. Centripetal acceleration is the acceleration directed towards the center of a circular path, while tangential acceleration is the acceleration along the direction of motion. In cases where an object is moving in a circular path at a constant speed, there is centripetal acceleration but no tangential acceleration.
When gradient increases what happens to the velocity?
When the gradient increases, the velocity typically increases as well. This is because a steeper gradient provides a greater driving force that accelerates the object moving along it.
