Click on the statement which is TRUE
Forces can not be created
Forces can change with speed
Forces are only single, not in pairs
To improve a car's speed and acceleration its air resistance should be
(a)
Which of these is not a type of force?
gravity
electromagnetism
speed
Fill in the blanks:
A force can be drawn using force
(a)
Forces always come in pairs. The pairs are called...
attractive pairs
interaction pairs
connecting pairs
close pairs
How do you measure forces?
with a newtonmeter
with a ruler
with a stopwatch
with a ruler and stopwatch
What does Hooke's Law state
When the extension doubles when you double the force
When the distance doubles when you double the force
When the length of a string doubles
Define the term "equilibrium"
when an object moves rapidly
when an object doesn't move because the forces cancel out
when an object slows down
Forces are measured in the unit...
(a)
Contact forces occur when objects are touching, examples of these include:
friction, gravity, pull
push, pull, friction
friction, air resistance and water resistance
friction, gravity, push
Non-contact forces occur when objects are not touching, these include:
elastic, stretch and magnetic
gravity, gravitational and magnets
magnetic, positive and negative
gravitational, electrostatic, and magnetic forces
Weight is the force of the Earth on an object, Select the right formula used to measure this
Weight (G) = Mass (g) x g (N/Kg)
Weight (N) = mass (kg) x g (N/kg)
Weight (N) = mass (g) x k (N/gr)
On a moving car, the forward force is larger than the backwards force, this means the vehicle will...
move faster in the forwards direction
stay at the same speed the entire journey
stop
As you move away from the Earth in a spacecraft, what happens to the gravitational field
gets weaker
gets stronger
stays the same
Define the term weight
a stretching force
a type of force
a piece of equipment
The force of the Earth on an object due to its mass
Trains and planes are streamlined in shape, what does the term "streamlined" mean
Balanced
Can change shape
Shaped to reduce resistance to motion from air or water.
Easy to bend
The force on an object moving through the air that causes it to slow down (also known as drag). This is the definition for...
(a)
Which two situations are considered to be at equilibrium
A stationary car
a plane landing
a boat sailing
being sat in a chair
Select the situations that are examples of unbalanced forces
A customer walking down a shopping aisle
a customer sat in a barber chair
a plane taking off
someone sat in VIP watching a movie in the cinema
Which force keeps us on the Earths surface
pull
gravity
air resistance
friction
