The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
How can the velocity of a car during breaking at a constant acceleration against time from the moment of applying the breaks?
The velocity of a car during braking with constant acceleration can be calculated using the kinematic equation: final velocity = initial velocity + acceleration * time. As the car brakes, the initial velocity decreases to 0 m/s (assuming the car comes to a stop), and the acceleration due to braking is negative. Therefore, the equation becomes: final velocity = -acceleration * time.
Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
Does a car undergo acceleration when you step on the brake?
No, when you step on the brake, the car undergoes deceleration. Braking causes the car to slow down by applying a force in the direction opposite to its motion, leading to a decrease in speed. Acceleration refers to an increase in speed or a change in velocity.
Why does the car not move or very slow upon acceleration?
I just got an oil change, did they not reconnect something?
Can a car move without wheels?
No it can't move but it can move by pushing it.Hard but it moves.
Is it true that In order to increase the rate of acceleration of a car you should apply more force to it?
Increasing the force applied to a car will increase its acceleration, as described by Newton's second law (F=ma). However, there are other factors besides force that also affect acceleration, such as the car's weight, friction, and air resistance. It's important to consider overall driving conditions and safety when applying force to a car.
What is the mass of the car if the net force on the car is 3000 N east?
To determine the mass of the car, we would need to know the acceleration of the car. Using Newton's second law (F = ma), we can rearrange the equation to find mass (m = F/a) if we know the acceleration. Without the acceleration value, we cannot calculate the mass of the car based solely on the net force.
Why is it that their is an acceleration when a car is moving?
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
