Please insert the information you know into Newton's Second Law (F=ma, that is, force = mass x acceleration), then solve for the unknown (in this case, the mass).
Newton's 2nd law states that force (F) = mass (m) x acceleration (a); 4500 = m x 5; m = 900 kg
F = ma = 15N = 5mmass = m = 3 kg
It is 3 kilograms.
The mass is 900 kg.
When we apply force on an object, it accelerates in the direction of applied force. This acceleration is directly proportional to the magnitude of force and inversely related to the mass of the object.
A shove on an open door will force it into movement (motion) and it will close. cw: Mass moves at a constant rate (including zero) when there is no force applied to it. With a force applied, the mass accelerates. Accelerates means it changes its motion.
No. If an object is being pushed with the same force, the acceleration will be lower if the mass of the object is higher. If the question refers to an object falling due to gravity, then the force is proportional to the mass. As the mass increases, so the force of gravity also increases and the acceleration will remain the same.
The object accelerates in the direction of the resultant force.
A 20-newton force would cause acceleration at 6 m/sec The acceleration is given by the formula F=ma (Force = mass x acceleration) so for the same mass, doubling the force doubles the acceleration for the same mass.
The object accelerates.
When we apply force on an object, it accelerates in the direction of applied force. This acceleration is directly proportional to the magnitude of force and inversely related to the mass of the object.
When an unbalanced force acts on an object, the weight of the object decreases.
A shove on an open door will force it into movement (motion) and it will close. cw: Mass moves at a constant rate (including zero) when there is no force applied to it. With a force applied, the mass accelerates. Accelerates means it changes its motion.
a mass accelerates uniformly when an external unbalanced and constant force is applied on it.
Object b has a smaller mass because Newton's second law says that F=ma ... or m=F/a ... or mass is inversely proportional to acceleration. Since the applied force (F) is the same in both situations and the acceleration (a) of object b is larger than that of object a, object b must be smaller than object a.
No. If an object is being pushed with the same force, the acceleration will be lower if the mass of the object is higher. If the question refers to an object falling due to gravity, then the force is proportional to the mass. As the mass increases, so the force of gravity also increases and the acceleration will remain the same.
F = ma, so if mass is constant, you need to double the force to double the acceleration. The answer is 20 N.
The object accelerates in the direction of the resultant force.
A 20-newton force would cause acceleration at 6 m/sec The acceleration is given by the formula F=ma (Force = mass x acceleration) so for the same mass, doubling the force doubles the acceleration for the same mass.
F = ma. The force applied to an object creates an acceleration depending on the mass of the object.
