Are motorcycle and car moving on a horizontal road with the same velocity if they are brought to rest by the application of brakes?

Are motorcycle and car moving on a horizontal road with the same velocity if they are brought to rest by the application of brakes?

Therefore, both will stop at the same distance.

Does the engine of a car moving in horizontal road in uniform speed do any work?

Force applied by the engine of the car against friction maintains its uniform velocity . This force is doing work as displacement occurs against frication. If f= force of friction and v=velocity of the car, work done in 1s by the engine = force of friction × constant velocity =fv.

When a truck and a car are moving on a plane road with the same kinetic energy?

Both the truck and the car had same kinetic energy and hence same amount of work is needed to be done. As retarding force applied is same for both, therefore, both the truck and the car travel the same distance before coming to rest.

Is velocity the same if two scooters are moving at the same speed but in opposite directions?

So the two bodies moving with same speed but in different directions have different velocities. Was this answer helpful?

When a vehicle is moving with a uniform velocity on a smooth horizontal road?

When vehicle moves with uniform velocity, the net force on the vehicle in horizontal direction is zero. So frictional force by road is zero. Whereas, when it accelerates, the frictional force would be in forward direction, i.e., in the direction of its acceleration.

When a vehicle is moving on a road in a straight line with uniform velocity?

Since the vehicle is moving with uniform velocity, thus its acceleration must be zero. The friction force exerted by the road on its tires equals the force provided by its engine. So, the acceleration of the vehicle is zero and thus the vehicle moves with uniform velocity. Was this answer helpful?

Can you accelerate if you are traveling at a uniform speed?

Assertion :It is possible to accelerate even if you are travelling at constant speed. Reason: In the uniform circular motion, even if the particle has the constant speed, it has an acceleration.

Which has the most kinetic energy?

Plasma possesses the most kinetic energy of the fundamental states of matter. This is because the particles in a plasma move faster than the particles in a solid, liquid or gas of the same substance.

When a car and a bike with the same kinetic energy are brought to rest?

So,if a car and a bike with the same kinetic energy are brought to rest by the application of brakes. The break of the car has to apply greater force than the break of the bike. Because,the mass of the car is surely greater than the bike. That’s why the bike gains more momentum than the car.

How is kinetic energy directly related to the weight and speed of the vehicle?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

What two objects have the same speed but different velocities?

It is possible for two objects with different velocities to have equal speeds. For example, if two objects move in opposite directions, but the magnitudes of their velocities are equal, then they will have the same speed despite having different velocity values.

Can velocity change its direction?

An object can have a changing direction of velocity, and this is still called an acceleration, but the acceleration itself need not change (constant acceleration, meaning its magnitude and direction stay the same).

Can velocity stay the same?

Speed is a scalar variable, meaning it is merely a number, but velocity is a vector, meaning it has both magnitude and direction. The speed must remain constant in order to maintain a constant velocity. A body can maintain a steady speed while changing directions (velocity).

How do a motorcycle’s braking and acceleration differ from those of other vehicles?

The difference in acceleration and braking abilities between motorcycles and other vehicles is that while a vehicle driver only needs to step on the foot brake to stop a vehicle, a motorcyclist must control separate brakes for front and rear wheels.

When a vehicle is moving with a uniform velocity on a smooth horizontal road then the power delivered by its engine must be?

Answer: The correct option is (d) Zero. Explanation: The cause of this is friction.

When riding in a car at a constant velocity What happens to you if the car comes to a sudden stop?

You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest. You move forward because the car seat exerts an unbalanced force on your body.

What will be the effect on the velocity of the motorcycle if its speed increases or decreases but its direction remains unchanged?

The velocity will decrease as velocity is a vector quantity which means that it has both magnitude and direction. Although direction may remain same, but velocity will decrease due to change in magnitude.
