What is the average speed of the bus that travels 450km in 5 hrs?
Suppose a truck and a car are both running at 40 km/hr.Which vehicle needs a greater force to stop and why?
Why the jeepney of mass 2000kg more difficult to stop than a tricycle of mass 1000kg?
the jeepney of mass 2000kg is more difficult to stop than the tricycle of mass 1000kg because the force applied to the former is greater than the latter. thus, a heavier object requiring greater force to move needs greater force to stop it or interfere its linear movement.
Which is harder to stop vehicle greater mass or less mass?
The greater the mass the greater the inertia. Thus if both vehicles were travelling at the same speed the vehicle with the greater mass would have the most inertia and thus be the hardest to stop.
What will stop a glacier from moving downhill?
There needs to be matter greater in size and density to stop it/
What are Iaac Newtowns laws?
If something is stopped it needs a force to move it. If something is move it needs a force to stop it.
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.
How does the weight of a car effect the stopping distance of a car?
The more the vehicle weighs, the harder the brakes must work to stop it and the more distance it will need to stop the vehicle. However, large trucks can brake easier with more weight because weight adds friction which helps to stop the vehicle. This still doesn't fully compensate for the total stopping distance needed for a large vehicle. Basicly what he means is the heavier the vehicle the more friction it can create(slow it down) but it can add to the forward force iswell Or more precisely, the force of the vehicle going forward because of it's mass is still greater than the force of friction helping the vehicle slow down.
Does traveling at a high speed require greater stopping distance?
Yes, traveling at a higher speed increases the kinetic energy of the vehicle, which means it will require a greater stopping distance to come to a complete stop. This is because the vehicle needs more time and distance to reduce its speed gradually.
What needs more force to stop a bus or a racing car with the same speed of 30 kph?
To stop a bus and a racing car traveling at the same speed of 30 kph, the bus typically requires more force due to its greater mass. According to Newton's second law of motion (F=ma), force is directly proportional to mass when accelerating or decelerating an object. Therefore, the bus's larger mass means it has more momentum, necessitating a greater force to bring it to a stop compared to the lighter racing car.
What force is used to stop a vehicle?
the friction caused by the road agianst tires
A car traveling along the highway needs a certain amount of force exerted on it to stop more stopping force may be required when the car has?
If the car has a higher mass, a higher velocity, more aerodynamic shape (thereby lower drag), or it's tires have a lower friction coefficient (meaning less of the force applied makes it to the ground), it will require more force to be applied to stop the vehicle.
Why is a brake pedal a second class lever?
A brake pedal is a second class lever because the effort force (your foot pressing on the pedal) is located farther away from the fulcrum (pivot point) than the resistance force (brake mechanism). This configuration allows for greater force to be applied to stop the vehicle effectively.
