Unbalanced forces - deceleration
Gemma Unbalanced forces - deceleration
What is deceleration?
The rate at which an object speeds up
The rate at which an object slows down
The rate at which an object changes direction
The rate at which an object remains stationary
Which of the following is an example of deceleration?
A car speeding up on a straight road
A cyclist maintaining a constant speed
A train moving at a constant speed on a curved track
A ball rolling down a hill
When an object experiences deceleration, what happens to its velocity?
It increases
It decreases
It remains constant
It changes direction
Which of the following is an example of an unbalanced force causing deceleration?
A book sliding on a frictionless surface
A rocket accelerating in space
A ball rolling on a flat surface
A car coming to a stop
Which of the following is true about the net force acting on an object experiencing deceleration?
It is equal to zero
It is greater than zero
It is less than zero
It depends on the mass of the object
What is the relationship between mass and deceleration?
As mass increases, deceleration increases
As mass increases, deceleration decreases
There is no relationship between mass and deceleration
Deceleration is inversely proportional to mass
Which of the following statements is true about deceleration?
It is always negative
It is always positive
It can be positive or negative
It is always zero
Which of the following factors affect the deceleration of an object?
Mass and velocity
Force and distance
Time and energy
Temperature and pressure
