Newton's third law states that (1 point) Any two objects in the universe attract each other with a force directly proportional to the product of

Newton's third law states that (1 point)
1. Any two objects in the universe attract each other with a force directly proportional to the product of the masses and inversely proportional to the square of the distance separating them.
2. For every action, there is an equal but opposite reaction.
3. An object will remain at rest or move in a straight line unless acted upon by a net force.
4. For every reaction, there is an equal reaction in the same direction.
5. The force acting on an object is directly proportional to the acceleration produced by the force.
Which of the following situations can be explained by Newton's first law? (1 point)
1. When the force acting on an object is doubled, its acceleration is doubled.
2. A swimmer pushing the water backward to move forward.
3. When the brakes of a car are applied suddenly, the body of the driver jerks forward.
4. When a man fires a gun, his body jerks backward.
5. When the force acting on an object is doubled, its acceleration is halved.
Mass of an object is (1 point)
1. the same as the weight of the object.
2. different on different planets.
3. a measure of the gravitational force exerted on the object by the massive object in the vicinity of the object.
4. a measure of the amount of matter the object has.
5. measured in terms of Newtons.
An object has a mass of 5.786 kg. Calculate its acceleration when acted upon by a force of 250 N. (1 point)
Calculate the mass of an object whose weight is 767 N. (1 point)
A force that causes an acceleration of 5 m s² on an object of mass 26.884 kg is acting on a 50 kg object. Calculate the acceleration of the 50 kg object. (1 point)
The component of the surface force between two surfaces sliding on each other parallel to the surface is called (1 point)
1. normal force
2. contact force
3. friction
4. gravitational force
5. sliding force
Which of the following is a correct statement? (1 point)
1. Coefficient of friction is equal to the ratio of normal force to force of friction.
2. Static coefficient of friction is less than kinetic coefficient of friction.
3. The unit of measurement for coefficient of friction is Newton / kg.
4. The force required to just get an object slding is bigger than the force required to slide it once it has started sliding.
5. Force of friction depends on the relative speed between the sliding surfaces.
An object of mass 72.987 kg is sliding on a horizontal surface. Calculate the normal force exerted by the surface on the object. (1 point)
An object of mass 42.333 kg is sliding on a horizontal surface with a uniform speed. The coefficient of kinetic fiction of the surfaces is 0.25. Calculate the force of friction exerted by the surface on the object. (1 point)
An object of mass 27.764 kg is being pulled by a horizontal force of 290 N on a horizontal force. The coefficient of kinetic friction between the object and the surface is 0.1. Calculate the acceleration of the object. (1 point)
