What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
A pendulum set in motion eventually stops because?
1). Air resistance 2). Friction in the pivot. These two effects rob energy from the pendulum. Without air resistance or friction in the pivot, a pendulum, once set in motion, would not stop.
If you have 70 red blocks and 84 green blocks what is the greatest number of identical block stacks that can be made without any blocks leftover?
100

Without friction there would be?
NO friction
Two identical freight cars roll without friction towards each other on a level track one rolls at 2ms and the other rolls at 1ms after the cars collide they couple and roll together with a speed of?
After the collision, the two freight cars will move together at a speed equal to the combined momentum of the two cars before the collision. This can be calculated using the conservation of momentum principle. The speed of the two cars together after the collision would be (2 m/s + 1 m/s)/2 = 1.5 m/s.
Can we drink from a glass without friction?
No, it is not possible to drink from a glass without friction. Friction is necessary to hold the liquid inside the glass and to help lift and drink from it without spilling.
What is express cargo?
Cargo or freight that is shipped without stops.
Can you not walk without friction?
No, walking without friction is not possible. Friction is necessary between the foot and the ground to generate the necessary traction for walking and to prevent slipping.
What is examples of friction?
The fact that you can walk without sliding is an example of friction.
What is impossible without friction?
Walking, running, or any form of movement on a surface would be extremely difficult without friction. Cars would have difficulty stopping or turning without friction between the tires and the road. In general, many everyday activities would be challenging without the presence of friction.
Is it legal for a commercial vehicle to carry freight without a bill of lading?
No.
Where is friction in cycling?
the friction is between the tyres of cycle and the road surface. Without friction movement is impossible.
Can you drink from a glass without friction?
No, it's not possible to drink from a glass without any friction. Friction is necessary for your lips to grip the glass and create a seal to prevent spillage. Without friction, the glass would slip out of your hands or the liquid would spill.
