Dynamics Review

An object with a mass of 5.0 kg is rest on frictionless surface. When the object is pulled by constant force of magnitude 25.0 N, what is the speed of object after 3 s?

n object with a mass of 5.0 kg is rest on frictionless surface. When the object is pulled by constant force of magnitude 25.0 N, what is the distance (in meter) after 4 s ?

n object with a mass of 5.0 kg is rest on frictionless surface. When the object is pulled by constant force of magnitude 25.0 N, what is the speed (in m/s) after it moved a distance 10.0 m?

Every object continues in its state of rest, or of uniform velocity in a straight line, as long as no net force acts on it. ​ (a)  

• Newton's First Law
• Newton's Second Law
• Newton's Third Law

The acceleration of an object is directly proportional to the ​ (a)   acting on it, and is inversely proportional to the object’s ​ (b)   . The direction of the acceleration is ​ (c)   of the net force acting on the object.

• net force
• mass
• in the direction
• in the opposite
• weight
• energy

Whenever one object exerts a force on a second object, the second object exerts an/a ​ ​ (a)   force ​ in the ​ (b)   direction on the first.

• equal
• opposite
• smaller
• bigger
• same
