Test: Effects of Forces - Question 1

When is the terminal velocity of an object reached?

Detailed Solution for Test: Effects of Forces - Question 1
This happens when the resistance of the fluid is the same magnitude (size) as the force causing the movement
Test: Effects of Forces - Question 2

Which of the following surfaces will have the greatest frictional force?

Detailed Solution for Test: Effects of Forces - Question 2
Drivers need to take more care when braking on smooth road surfaces especially when they are wet as friction is lower

Test: Effects of Forces - Question 3

The equation that links mass, force and acceleration is ...

Detailed Solution for Test: Effects of Forces - Question 3
This is Newton's second law. You will need to be able to rearrange it to work out the mass or acceleration when given the other two figures
Test: Effects of Forces - Question 4
When a resultant force acts upon an object, what determines the size of the acceleration of that object?
Detailed Solution for Test: Effects of Forces - Question 4
Larger masses will be accelerated more slowly for the same resultant force. Using a larger resultant force on a given mass will cause it to accelerate faster (and vice-versa of course for both cases!)
Test: Effects of Forces - Question 5
How can distance travelled be calculated by using a velocity time graph?
Detailed Solution for Test: Effects of Forces - Question 5
If you sum up the area underneath a velocity-time graph, you have calculated the distance an object has travelled in a given time
Test: Effects of Forces - Question 6
As the speed of a car increases, what happens to the strength of the air resistance?
Detailed Solution for Test: Effects of Forces - Question 6
Air resistance is caused by the car hitting the molecules of the gases that make up the atmosphere
Test: Effects of Forces - Question 7
What can affect the speed of a car?
Detailed Solution for Test: Effects of Forces - Question 7
It is all about resultant forces and inertia
Test: Effects of Forces - Question 8

What happens to the motion of an object when the forces acting on it are balanced?

Detailed Solution for Test: Effects of Forces - Question 8

When the forces acting on an object are balanced, the resultant force is zero. According to Newton's First Law of Motion, the object will continue to move with constant velocity (including being at rest if initially at rest).

Test: Effects of Forces - Question 9

Which type of force always acts in the opposite direction to the motion of an object moving through a fluid (like air or water)?

Detailed Solution for Test: Effects of Forces - Question 9

Resistive force, such as air resistance or drag in water, acts opposite to the direction of motion of an object moving through a fluid.

Test: Effects of Forces - Question 10

What is the effect of applying a force to an object?

Detailed Solution for Test: Effects of Forces - Question 10

Applying a force to an object changes its state of motion. It can cause it to accelerate, decelerate, or change direction depending on the direction and magnitude of the force applied.
