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.
Does high velocity affect rate of change of velocity?
Yes, high velocity can affect the rate of change of velocity. If an object is already moving at a high velocity, it may require more time or force to change its velocity compared to an object moving at a lower velocity due to inertia.
Which is having a higher value of momentum - a bullet of mass 10G moving with a velocity of 400m's or a cricket ball of mass 400G thrown with the speed of 90km?
I am assuming that you meant the speed of the cricket ball to be 90km/h.Momentum = mass in kg x velocity in m/sThe BulletConvert the mass from grams to kilograms.10g x (1kg/1000g) = 0.01kgMomentum of the bullet is 0.01kg x 400m/s = 4kg•m/sThe Cricket BallConvert km/h to m/s.90km/h x (1000m/1km) x (1h/3600s) = 25m/sConvert g to kg.400g x (1kg/1000g) = 0.400kgMomentum of the cricket ball = 0.400kg x 25m/s = 10kg•m/sAnswer: The cricket ball has the greater momentum.
Is it true that a slow moving object has more kinetic Energy fast moving objects?
No, kinetic energy is dependent on both an object's mass and velocity according to the equation KE = 0.5 * mass * velocity^2. A faster moving object will generally have more kinetic energy compared to a slower moving object of the same mass.
What velocity means?
If you have no velocity, then you aren't moving.
Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?
When an object is moving at a constant velocity, it means that the forces acting on it are balanced. In this case, the force of kinetic friction is equal and opposite to the applied force, making it easier to calculate the coefficient of kinetic friction using the known values of force and normal force.
What are difference between speed and velocity?
Speed is a scalar quantity that reflects how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. Speed is the magnitude of velocity. Velocity provides a more comprehensive description of an object's motion compared to speed.
What are diifferent word for object?
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
How does air cause a pressure against a car windscreen?
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.
How much kinetic energy in a fast moving cricket ball?
The kinetic energy of a cricket ball depends on its mass and velocity. For example, a cricket ball weighing 160 grams and traveling at a speed of 140 km/h (38.89 m/s) would have a kinetic energy of about 110 joules.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
When is velocity negative in a moving object?
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
