How is weight different from mass?
Weight is the same as mass
Weight is the force a body exerts on the ground, found by multiplying mass and the acceleration of gravity
Weight is measured in kilograms, while mass is measured in newtons
Weight is only relevant in space
What does inertia describe?
The speed of an object
The reluctance of a body to change its state of motion
The force required to move an object
The energy stored in a moving object
Which of the following is generally classified as an internal force in sport?
Gravity
Air resistance
Friction
Contraction of skeletal muscles
What is the main purpose of a cyclist wearing an aerodynamic suit and helmet?
To increase friction
To reduce the dragging effect of air resistance
To increase speed by adding weight
To improve muscle contraction
Which of the following is the correct formula for impulse?
impulse = force + time
impulse = force × time
impulse = force ÷ time
impulse = time ÷ force
What does the mnemonic "BEST" stand for in relation to force summation?
Balance, Energy, Speed, Timing
Body parts, sEquence, Stabilisation, Timing
Body, Energy, Sequence, Time
Balance, Endurance, Strength, Technique
Which of the following is an example of a momentum breaker?
A golfer driving a golf ball
A footballer kicking a football
A cricketer catching a ball
A tennis player serving a ball
Why does the amount of rotation an object has depend on where the force is applied?
Because the force changes direction
Because the distance from the axis of rotation affects the torque produced
Because the object becomes lighter
Because the force is always the same
Which statement about angular displacement is correct?
It is always equal to angular distance
It is measured by the larger of the two angles
It has both magnitude and direction
It is only measured in clockwise movements
If the angular displacement is 120° and the time taken is 2 seconds, what is the angular velocity?
60°/s
120°/s
240°/s
2°/s
What challenge might a young child face when using a large baseball bat, according to the text?
The bat will be too light to swing
The bat will have a large moment of inertia, making it hard to swing
The bat will increase their angular velocity
The bat will make them run faster
If the same force is applied to two objects of different masses, which object will experience greater acceleration?
The object with greater mass
The object with smaller mass
Both will have the same acceleration
Acceleration does not depend on mass
Which formula should you use to calculate acceleration when given force and mass?
a = F / m
a = m / F
a = F × m
a = m - F
If a lever has a mechanical advantage greater than 1 (>1), what will it increase?
Force (ARF)
Speed (AFR)
Length
Weight
Given a lever where the force arm is 2 and the resistance arm is 5, what is the mechanical advantage?
0.4
2.5
7
10
