What explains why the cart always catches the ball and the ball doesn't fall behind the moving cart?
Because the ball and the cart are moving at the same forward speed.
What is the momentum of a 8 kilogram cart moving with a speed of 12 meters per second?
96 kgm/s.
When mass is added to a moving cart what happens to its 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.
What happen to the speed of a cart when a horse applies more force?
The speed of cart becomes fast when the horse applies more force
Why would a cart start moving faster if you gave it a hard push than if you gave it a soft push?
When u push the cart,u apply some force on the cart which does the work(the cart moves). The movement of the cart is the work done due to the application of the force you.
What explains why the cart always catches the ball and the ball doesn't fall behind the moving cart?
Because the ball and the cart are moving at the same forward speed.
What are the answers to the quiz on Gizmo Force and fan carts?
A fan cart with the fan set to High rolled across a floor. The cart's speeds are shown below. If the fan were set to Medium instead, what could the cart's speed be at 5 seconds? A. 10.9 cm per secondB. 31.0 cm per secondC. 40.1 cm per secondD. 48.3 cm per secondCorrect Answer: A - 10.9 cm per second Explanation: The fan supplies a force to the cart. If a lower fan speed were used, less force would be applied. This would cause a slower change in the cart's speed. So, the cart would be rolling more slowly than 31.0 cm per second after 5 seconds. The only choice that is less than 31.0 cm per second is 10.9 cm per second.Force is needed A. for a moving object to keep moving at the same speed and directionB. for a moving object to change its speedC. for a motionless object to remain stillD. to prevent a moving object from turningCorrect Answer: B - for a moving object to change its speed Explanation: An object will change its speed only if a force acts on it. In the Gizmo, forces can speed the cart up (fan) or slow the cart down (friction). Answer choice A is incorrect because a moving object will keep moving at the same speed if there is no force acting on it (like the cart after the fan was turned off). Answer choice C is incorrect because no force is required for a motionless object to remain at rest. Answer choice D is not correct because a moving object will naturally move in a straight line if there is no force.Rebecca puts her backpack on a fan cart and turns the fan on. She then measures the speed each second afterward. At 10 seconds the cart has a speed of 20 cm per second. How fast will the cart be moving at 12 seconds? A. 18 cm per secondB. 20 cm per secondC. 22 cm per secnodD. 24 cm per secondCorrect Answer: D - 24 cm per second Explanation: The cart started at 0 cm per second. Ten seconds later it was moving 20 cm per second. Therefore, every second the cart is gaining 2 cm per second. So, after 11 seconds the speed will be 22 cm per second. After 12 seconds the speed will be 24 cm per second.A fan cart is moving forward on a frictionless surface. If you change the fan speed from High to Low, what will occur? A. The cart will stop moving.B. The cart will slow down.C. The cart will keep moving at the same speed.D. The cart will continue to speed up, but not as quickly as before.Correct Answer: D - The cart will continue to speed up, but not as quickly as before. Explanation: The cart will continue to speed up because there is still force acting on it. However, less force is acting on it now because the fan speed is lower.The speed-versus-time bar graph for a fan cart experiment is shown below. What could have happened? A. The track was frictionless, and the fan was changed from High to Low after 8 seconds.B. The track was frictionless, and the fan was changed from High to Off after 8 seconds.C. The track was wooden, and the fan was changed from High to Off after 8 seconds.D. The track was wooden, and the fan was changed from Off to Low after 8 seconds.Correct Answer: B - The track was frictionless, and the fan was changed from High to Off after 8 seconds. Explanation: The bar graph shows that the speed stayed the same after 8 seconds. This means there is no total force on the cart. This matches the situation in which the fan is off and the surface is frictionless.
What is the momentum of a 8 kilogram cart moving with a speed of 12 meters per second?
96 kgm/s.
An 80 kg cart moving at 70 Km per hour collides head on with an approaching 120 kg cart moving at 40 Km per hour ''In The Opposite Direction''. If the two carts stick together what will be their speed?
The answer is 4.
How do you get the cart moving in Nabooti in Poptropica?
you push the cart then jump on it

What is the describing word of cart?
moving
What is Aristole's horse cart theory?
Aristotle's horse-cart theory is a metaphor he used to explain the relationship between motion and change. Similar to how a horse pulls a cart, Aristotle believed that motion is caused by a force or "prime mover" that initiates change in the world. This prime mover is an immutable, eternal being that sets everything else in motion.
Do a truck and a golf cart have the same kinetic energy?
When they're parked they do (which is zero). If a truck and golf cart were both moving at the same non-zero speed, the truck, being more massive, would have the greater kinetic energy.
What happen to the speed of a cart when a horse applies more force?
The speed of cart becomes fast when the horse applies more force
A cart is 10 cm long It travels through a photogate in 2 seconds what's the cart's speed?
V = 10cm/2s = 5cm/s Therefore, the cart's speed is 5cm/s.
How can one use beach cart easily?
One can maneuver a beach cart as easy as it is. The beach cart is designed with wheels that are resistant to rough gritty surfaces, which can be pulled or pushed with ease.
