Total questions: 20
Worksheet time: 10mins
1. When an object is at rest on a surface - what can you say about the forces on it?
they are all equal
they are unbalanced
all the forces cancel out so the net force is zero
all the forces are in the same direction
2. Force is considered to be a vector quantity. Which is a correct statement about a vector quantity?
Has direction only
Has neither magnitude nor direction
Has direction and magnitude
Has magnitude only
3. The …….. forces will have no effect on the movement of an object
Unbalanced
Balanced
Opposite
Identical
4. When an object is not moving what effect will balanced forces have on the object?
it will start moving
it will speed up
it will slow down
it will not move
5. When an object is moving - what effect will a balanced force have on the object?
it will start moving faster
it will speed up to a steady speed
it will slow down
it will not move
6. Describe the motion of a rest object if an unbalanced force acts on it
no change
it will accelerate
It will decelerate
it will accelerate or decelerate depending upon the forces
7. Describe the motion of a moving object if an unbalanced force acts on it
no change
it will accelerate
It will decelerate
it will accelerate or decelerate depending upon the forces
8. How will the mass of the object affect the way it accelerates?
no effect
more massive objects are easier to accelerate and harder to decelerate
more massive objects are harder to accelerate and harder to decelerate
more massive objects are easier to accelerate and easier to decelerate
9. How will the force act on the object affect the way it accelerates?
no effect
The bigger force the bigger acceleration
The bigger force the smaller acceleration
The smaller force the bigger acceleration
10. look at the picture, What is the resultant force?
40 N to the Left
40 N to the Right
20 N to the Right
0 N
11. Look at the picture. What is the resultant force?
0 N
20 N
35 N
55 N
13. look at the picture, What is the resultant force?
15 N
20 N
25 N
30 N
14. The property of a object at rest to remain at rest is known as
Inertness
Inertia
Resistance
sluggishness
15. What does Newton’s first law state?
A body at rest tends to remain at rest and a body in motion tends to remain in motion at a constant velocity unless acted on by a net external force.
A body at rest tends to remain at rest and a body in motion tends to remain in motion at a constant acceleration unless acted on by a net external force.
The rate of change of velocity of a body is directly proportional to the external force applied to the body.
The rate of change of velocity of a body is inversely proportional to the external force applied to the body.
16. look at the picture below!
which is the example of Newton's 3rd Law?
16. How much force needs to be applied to a 10 kg object for it to accelerate at 20 m/s2?
200 N
150 N
100 N
50 N
17. What is the acceleration if a 400 N of force acts to a 80 kg of object?
10 m/s2
8 m/s2
5 m/s2
4 m/s2
18. an object is acted a 500 N of force and accelerated 2 m/s2. what is the mass of the object?
500 kg
300 kg
250 kg
200 kg
19. Newton’s second law describes the relationship between which quantities?
Force, mass, and time
Force, mass, and displacement
Force, mass, and velocity
Force, mass, and acceleration
20. What is Newton’s third law of motion?
Whenever a first body exerts a force on a second body, the first body experiences a force that is twice the magnitude and acts in the direction of the applied force
Whenever a first body exerts a force on a second body, the first body experiences a force that is equal in magnitude and acts in the direction of the applied force.
Whenever a first body exerts a force on a second body, the first body experiences a force that is twice the magnitude but acts in the direction opposite the direction of the applied force.
Whenever a first body exerts a force on a second body, the first body experiences a force that is equal in magnitude but acts in the direction opposite the direction of the applied force.
