To keep a sled accelerating downhill what must the force of gravity be greater than?
To keep a sled accelerating downhill, the force of gravity must be greater than the force of friction acting against the sled. This allows gravity to overcome the frictional force and propel the sled forward.
Why the force may be greater than equal to or less than the weight of the liquid in the container?
I believe that would be gravity, acceleration and momentum.
What kind of force do you need to stop a more massive object?
To stop a more massive object, you typically need a force that is greater than the object's momentum. This force must act in the opposite direction of the object's motion in order to decelerate it and eventually bring it to a stop. The larger the mass of the object, the greater the force required to stop it.
When would the linear momentum of a truck be greater than that of a bus?
The linear momentum of a truck would be greater than that of a bus if the truck has a larger mass or is moving at a higher velocity compared to the bus. Linear momentum is directly proportional to the mass and velocity of an object.
The amount of force that you must use on an object to lift it is?
Any force greater than its weight.
What will make an object accelerate faster one with less inertia or more momentum?
If an object has more momentum, it has either a greater mass or a greater velocity. If an object has less inertia, it has less mass. So am object with less inertia will accelerate faster than one with greater momentum because of a greater mass, assuming the same force of acceleration is applied to both. However, if the greater momentum is due to greater velocity, not enough information has been provided to answer the question.
When a force is exerted on an object does a large force always produce greater change in the object's momentum than a smaller force does explain?
No this causes an unbalanced force or a balanced forceNO chizz you rape the poor person!
When you kick a football what action and reaction forces are involved Which force if any is greater?
When you kick a football, the action force is the force exerted by your foot onto the ball, and the reaction force is the force exerted by the ball back onto your foot (Newton's third law). The force applied by your foot is likely greater than the force exerted back by the ball since your foot can generate more power and momentum.
Why does a car speeding up on the highway have a greater force than a car slowly driving into a garage?
Because it has more momentum the faster it goes.
The momentum before a collision of three objects is always greater than tha momentum after the collision?
Not necessarily. The total momentum of a system of objects is conserved unless external forces are present. In a collision involving three objects, the total momentum before the collision could be equal to, greater than, or less than the total momentum after the collision, depending on the specific circumstances of the collision.
Is it true that a sled accelerating downhill the force of gravity must be greater than the normal force?
Yes, when a sled is accelerating downhill, the force of gravity pulling the sled downhill must be greater than the normal force acting in the opposite direction to overcome friction and any other resistive forces. This difference in force is what allows the sled to accelerate downhill.
Which is greater the momentum of a bullet fired from a rifle or the momentum of the rifle's recoil?
The momentum of the bullet fired from a rifle is greater than the momentum of the rifle's recoil. This is because the bullet has a higher velocity and mass compared to the rifle, resulting in a greater momentum.
