In a curved path with constant speed the acceleration is the centripetal acceleration given by the equation acen=v2r.

How does a ramp affect acceleration?
The speed/velocity of the car will gradually increase by the same amount every second. The steeper the slope (the bigger the angle of inclination of the ramp) that the car is rolling down, the faster the car will accelerate. This is because the amount of gravity experienced is dependent on the angle of the slope.
Why do things roll faster down a steeper slope?
This is because moving up or down a hill changes one kind of energy into another. Objects at the bottom of the hill have more kinetic energy, which means they are moving faster.
WHAT IS curve in motion?
The motion of an object moving in a curved path is called curvilinear motion. Example: A stone thrown into the air at an angle. Curvilinear motion describes the motion of a moving particle that conforms to a known or fixed curve.
What is curvilinear motion in physics?
Definition of curvilinear motion : motion in which the direction of the velocity of a body is variable and the path of the body is a curved line.
What forces affect motion along a curved path?
If an object is moving along a curved path, the direction of its velocity is changing. The force responsible for this change in direction is called centripetal force which means center-seeking force.
Does the angle of a ramp affect speed?
The rate at which the object slides down the surface is dependent upon how tilted the surface is; the greater the tilt of the surface, the faster the rate at which the object will slide down it. In physics, a tilted surface is called an inclined plane.
Does steepness of a ramp affect acceleration?
If you increase the steepness of the ramp, then you will increase the acceleration of a ball which rolls down the ramp. This can be seen in two different ways: 1) Components of forces. Forces are vectors and have a direction and a magnitude.
What happens to acceleration if the angle of the ramp is increased?
As the angle of incline increases, acceleration will increase.
Why do heavier objects roll down a ramp faster?
There will be a resultant force which will be proportional to the mass of the object. Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object.
Does the height of a ramp affect speed?
If the ramp is steep, the force of gravity can more easily overcome the force of friction. Obviously gravity will cause an object on an incline to move down the slope faster than a flat slope.
How does the angle of a ramp affect the speed of a rolling ball?
The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach. The greater the mass of the ball, the greater velocity the ball will reach.
What is curvilinear motion example?
Curvilinear motion is the motion of an object when it moves along a curved path. So the movement of a snake and a roller coaster are curvilinear in nature as they move in a curved fashion eventhough it forward in a straight line. A train moving on a curved track is also an example of curvilinear motion.
Can linear motion curved?
In linear motion, the particles will move from one point to another point either in a straight line or a curved path. Basically, in linear motion an object travels the same distance at the same time and the object can move in a straight or a curved path from one point to another.
What are the two types of curvilinear motion?
Curvilinear systems generally take one of two forms: simple, constant-radii sections (such as a 90- or 180-degree turn) together with straight sections, or variable-radii sections (think of a free-form, squiggly line) combined with straight sections.
What is the difference between curvilinear and circular motion?
Circular motion is defined as the movement of an object around the circular path from a fixed distance. For example-movement of the hands of a clock. Curvilinear motion is defined as the movement of an object along a curved path. For example- a stone or ball thrown by a boy.
What is curvilinear force?
When a particle moves from one point to another in a curved path, the motion of the particle in such a case is known as curvilinear motion. In the case of curvilinear motion, two types of force come into the picture, i.e., the centrifugal force and centripetal force.
Is circular motion is a curvilinear motion?
Circular motion is a special case of curvilinear motion in which the radius of rotation remains constant. In this case there is an acceleration towards the cente of ฯ2r. This gives rise to a force towards the centre known as the centripetal force. This force is reacted to by what is called the centrifugal reaction.
Why do projectiles move in a curved path?
Earth’s gravity acts downward toward the center of Earth. Why does a projectile follow a curved path? The combination of intitial forward velocity and downward vertical force of gravity cause of projectile to follow a curved path.
What causes an object to move in a circular path?
A centripetal force is a net force that acts on an object to keep it moving along a circular path.
What motion is the movement of an object in a curved path toward the ground?
Projectile motion is movement of an object in a curved path toward the ground because it has both a horizontal force and the downward force of gravity acting on it. Examples of objects that have projectile motion include arrows and cannon balls.
How does the angle of a ramp affect maximum height?
The maximum height is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the maximum height.
How does slope affect velocity?
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
How do you find the acceleration of a ramp?
Acceleration on a ramp equals the ratio of the height to the length of the ramp, multiplied by gravitational acceleration. Acceleration on a ramp equals the sine of the ramp angle multiplied by gravitational acceleration.
