force and acceleration

an object with mass 30.0kg moving with acceleration 2.0m/s2 the force that is effect on the object is

• 60N

• 15N

• 20N

• 22N

the direction of the gravity force is

• down

• up

• right

• left

when we put the book above the table write the forces that affected on the book and their direction

how many forces that effect on car moving with constant velocity?

newton second law is

• force = mass*acceleration

• force = mass/ acceleration

• acceleration = mass/ force

• N

a car is moving with constant speed with mass 1000kg if the speed of this car is 26 m/s the force it will be

• 26000 N

• 13000 N

• 0 N

• 28000

an object is moving from rest to 20.0m/s within 10 s if this object is 24 kg the force will be

• 25 N

• 0 N

• 24N

• 48 N
