Which shopping cart is easier to stop physics problem?
In terms of stopping a physics problem involving a shopping cart, it would be easier to stop a cart with a lower mass and slower velocity. This is because the stopping distance is directly related to the mass and velocity of the object. A lighter cart moving at a slower speed will be easier to stop compared to a heavier cart moving at a faster speed.
What can you say about the motion of the cart is it in uniform motion or is it accelerating?
If the cart is moving at a constant speed in a straight line, it is in uniform motion. If the cart is changing its speed or direction, it is accelerating.
What explains why the cart always catches the ball and the ball doesn't fall behind the moving cart?
The cart and the ball are both subject to the same gravitational acceleration, so they fall at the same rate. The cart's horizontal motion keeps pace with the vertical motion of the ball, allowing it to catch up. This is the principle of inertia and the relationship between vertical and horizontal motion.
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 is the momentum of a 8 kilogram cart moving with a speed of 12 meters per second?
The momentum of an object is calculated by multiplying its mass and velocity. In this case, the momentum of the 8 kg cart moving at 12 m/s would be 96 kg*m/s.

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.

you push the cart then jump on it

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?
When a horse applies more force to a cart, the speed of the cart will increase. This is due to Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force applied to it. So, the greater the force applied by the horse, the faster the cart will accelerate and increase in speed.
If you push a shopping cart and one wheel hits a rough patch of concrete it is difficult to steer the cart in a straight line. How is this similar to refraction of a wave as it enters a new medium?
When a shopping cart wheel hits a rough patch, it experiences a change in direction due to the difference in surface. Similarly, when a wave enters a new medium with a different density, it changes direction due to the change in speed of the wave. This change in direction is known as refraction, where the wave bends towards or away from the normal depending on the difference in the speed of the wave in the two mediums.
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.
