What is the conclusion of the cart on a ramp lab?

Conclusion. According to both experiments and analysis, we can confidently conclude that when a cart is traveling down a ramp, it gradually speed up and experience an uniform acceleration.

When a cart is moving with constant velocity the force on the cart must be?

1 Expert Answer And since we know the velocity is constant, that means acceleration is 0. If acceleration is 0, the net horizontal force on the cart is also 0. This means that the force towards the right has to equal the friction force towards the left.

Is the acceleration of the cart constant as the cart moves down the ramp?

It’s a constant acceleration which means that it remains the same as long as the cart is sliding down the ramp. Let’s try to measure that acceleration and then use it to explore some basic physics of motion.

When a car and a truck are moving with the same momentum?

The mass of the car is less than the mass of the truck, If the momentum of car and truck is the same ( P car = P truck ) then the speed of the car is greater than the speed of the truck. ( V car > V truck ) . This is because at constant momentum the mass is inversely proportional to the velocity of the object.

How do you write a conclusion for a lab experiment?

1. briefly restate the purpose of the experiment (i.e. the question it was seeking to answer)
2. identify the main findings (i.e. the answer to the research question)
3. note the main limitations that are relevant to the interpretation of the results.

What is the cart on a ramp experiment?

This experiment uses an incline and a low-friction cart. If you give the cart a gentle push up the incline, the cart will roll upward, slow and stop, and then roll back down, speeding up. A graph of its velocity vs. time would show these changes.

Who continues to apply a force in order to move a cart with a constant speed explain why?

But in this case the horse has to continuously exert the force to move the cart, this is because the force of friction is acting against the motion of the cart which us opposing its motion. So the horse has to apply force to overcome this force of friction.

What is the relationship between the force acting upon a moving cart and its acceleration?

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

How is the kinetic energy of a moving cart affected if?

Hence, the kinetic energy of the moving cart is two times its initial value in case of mass is doubled and the kinetic energy reduces to one-ninth of its initial value in case the velocity is reduced to one-third of the initial velocity.

Is velocity positive or negative?

Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive. Another way to say this is that speed is the absolute value of velocity.

What is the formula for acceleration down 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.

What happens when a constant force is exerted on a cart that is initially at rest on an air track?

A constant force is exerted for a short length of time on a cart that is initially at rest on an air track. This force gives the cart a certain final speed. The same force is exerted for the same length of time on another cart, also initially at rest, that has four times the mass of the first one.

What was the conclusion of the ball and ramp experiment?

To conclude the results, the higher the incline, the faster the ball would roll down the ramp, which made the time decrease as well.

What is the objective of the inclined plane lab?

Purpose: To determine the mathematical equation which relates the weight of an object to the component of the weight which is directed parallel to an inclined plane.

What was the conclusion of the terminal velocity experiment?

Conclusion. This experiment was performed to analyze how mass affects terminal velocity. Before conducting this lab, it was hypothesized that as mass increases, the terminal velocity will increase. As seen in the graphs above, the hypothesis was proven true.

Why does a cart accelerate down a ramp?

A cart rolling down a ramp will accelerate due to gravity. The acceleration due to gravity for an object falling straight down is . The acceleration of an object down a ramp angled at angle is affected by the factor . Depending upon the angle, the expected acceleration due to gravity was given by ⁄ .
