Can an object accelarate without friction?
Yes, an object can accelerate without friction. The only thing that is needed to accelerate an object is net force acting on it should not be zero. Then the accleration of body is given by Newton's 2nd Law: F = m*a . For example Rockets in space experience no friction, but they accelerate due to force on them by the exhaust gases.
What type of friction is Throwing?
Throwing involves dynamic friction, which is the type of friction that occurs between two surfaces in relative motion. When an object is thrown, the friction between the object and the hand provides the force needed to accelerate the object and give it velocity.
What is needed to make an object accelerate?
To make an object accelerate, a force needs to be applied to the object. This force can come from various sources such as gravity, friction, or propulsion. The magnitude and direction of the force will determine the rate at which the object accelerates.
What quantity unit is called a newton?
A newton is the unit of force in the International System of Units (SI). It is defined as the amount of force needed to accelerate a mass of one kilogram by one meter per second squared.
The force needed to overcome kinetic friction is usually less than that needed to overcome static friction true or false?
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
What force in newtons is needed to accelerate a 2kg mass at 7 ms squared?
acceleration...

Is a K'Nex roller coaster faster when lighter?
It depends on the amount of friction. Higher friction means a higher resistance between the track and coaster which means it is slower. The weight of the coaster does not matter at all. F=ma a=9.8 m/s/s As mass increases, the force needed to accelerate at 9.8 metres per second squared is increased.
What type of friction is Throwing?
Throwing involves dynamic friction, which is the type of friction that occurs between two surfaces in relative motion. When an object is thrown, the friction between the object and the hand provides the force needed to accelerate the object and give it velocity.
How much force is needed to accelerate a mass of 160kilogram by 2meters per second squared?
F = (M) x (A) = (160) x (2) = 320 newtons.
What is needed to make an object accelerate?
To make an object accelerate, a force needs to be applied to the object. This force can come from various sources such as gravity, friction, or propulsion. The magnitude and direction of the force will determine the rate at which the object accelerates.
What is the net force needed to accelerate a 55kg cart at 15m per second squared?
F = (mass) x (acceleration) = (55) x (15) = 825 newtons.
How does a car accelerate speed?
A car accelerates when the engine produces more power than what is needed to overcome friction. The car reaches its maximum speed (on the level) when all the engine power is being used to overcome friction.
How much force is needed to accelerate a 3 kg mass at a rate of 9 m per second squared?
F = ma = 3kg x 9m/s2 = 27N
How much force is needed to accelerate a 68 kg-skier at a rate of 1.2 meters per sec squared?
66.8
