  Pull

 Push or Pull

 Push

Question 1 of 10

2. One way that you can recognize that a force is acting on an object:

  is to note any change in the objects state of motion.

 is to determine its mass at different locations.

 is to measure the instantaneous velocity of a moving object.

 A and C

Question 2 of 10

3. A 1-kg object is lying on the ground. An unbalanced force of magnitude 1 N is applied to the object. Which of these options explains the motion of the object as a result of the acting force?

 The object will accelerate in the direction of the applied force.

 The object will accelerate in a direction perpendicular to the applied force.

 The object will decelerate in the direction of the applied force.

 The object will remain at rest.

Question 3 of 10

4. If an object experiences a net zero unbalanced force, then the body:

 Cannot remain at rest.

 Can be accelerated.

 Moves with a constant velocity.

 Will always remain at rest.

5. Identify from the following, the case where balanced force acts on it.

 A person resting on an armchair.

 A lorry travelling at a variable speed on a straight road.

  A cyclist braking.

  A car that has a deceleration of 10 m/s²

Question 5 of 10

6. A force of 10 N acts on a ball moving on a surface. The force of friction that must act between the surface of the ball and the surface so that the ball keeps on moving with constant velocity over the surface must be:

 Zero

 20N

 10N

  100N

Question 6 of 10

7. ___________ is a force, which always opposes the motion of one body over the other body in contact with it

 Gravitational force

 Reaction force

 Normal force

 Frictional force

Question 7 of 10

8. If an object moves with a uniform velocity we can conclude that

 there is no force acting on the body

  no unbalanced force acts on it

 an unbalanced force acts on the body

  it has uniform acceleration

Question 8 of 10

9. When a force is exerted on an object, it can change its:

 State

  Position

 Shape

 All the above
