How can we calculate the speed of an object?
Speed= distance / time
Oops!
Okay!
The amount of kinetic energy of an object depends on ........................ and.....................
the mass and the speed of object.
Oops!
Okay!
GR. The speed of a truck is more than that of a car when both of them move down a ramp.
because the truck has more mass as the speed of the moving object on a ramp increases by increasing its mass.
Oops!
Okay!
GR. A truck needs a bigger engine than that of a small car to move with the same speed.
as the truck has more mass and kinetic energy than the car, so the truck needs a bigger engine than the car.
Oops!
Okay!
When the inclination of a ramp decreases, the kinetic energy of a ball rolling down ..........................
decreases
Oops!
Okay!
The smaller the mass of the vehicle, the less fuel it consumes. ( true/false)
True

on collision energy is ..............................
transferred and changed
Oops!
Okay!
The energy that can be heard and usually produced when two objects collide with each other.
Sound energy
Oops!
Okay!
GR. Driving fast is very dangerous.
because if a car increases its speed, its kinetic energy increases which result in exerting a large force during an accident.

Okay!
The distance that an object traveled in a certain amount of time.
