WorksheetsExploring Force, Momentum, and Torque
Total questions: 15
Worksheet time: 8mins
What is the definition of force?
Force is an interaction that causes an object to change its velocity.
Force is the mass of an object multiplied by its acceleration.
Force is a type of energy that can be stored.
Force is the distance an object travels over time.
How do you calculate momentum?
p = m * v
p = m - v
p = m / v
p = m + v
What is the formula for momentum?
p = m + v
p = m/a
p = mv^2
p = mv
What does the Law of Conservation of Momentum state?
Momentum can be created or destroyed in a system.
Momentum is only conserved in elastic collisions.
The total momentum of an open system changes over time.
The total momentum of a closed system remains constant.
Can you give an example of the Law of Conservation of Momentum?
A car accelerating down a straight road.
A ball thrown in the air.
A rocket launching into space.
Two ice skaters pushing off each other.
What is torque?
Torque is a measure of an object's mass.
Torque is the linear force applied to an object.
Torque is the rotational force applied to an object.
Torque is the speed at which an object rotates.
How is torque calculated?
Torque = Force + Distance
Torque = Force x Distance x sin(θ)
Torque = Distance / Force
Torque = Force / Distance
What units are used to measure torque?
Kilograms (kg)
Joules (J)
Watts (W)
Newton-meters (Nm) and foot-pounds (ft-lb)
What is an example of torque in everyday life?
Carrying a heavy box with both hands.
Using a hammer to drive a nail.
Using a wrench to tighten a bolt.
Pushing a door open with your hand.
How does torque affect the rotation of an object?
Torque is irrelevant to angular velocity.
Torque affects the rotation of an object by determining the angular acceleration and the speed of rotation.
Torque only affects linear motion.
Torque has no effect on rotation.
What happens to momentum in a closed system?
Momentum can be created in a closed system.
Momentum increases in a closed system.
Momentum is conserved in a closed system.
Momentum is lost in a closed system.
How can you increase torque on a lever?
Use a heavier lever material
Decrease the force
Increase the force or increase the distance from the pivot.
Shorten the lever arm
What is the relationship between force and torque?
Torque is the rotational effect of a force applied at a distance from a pivot point.
Force is only applicable in linear motion.
Torque is the same as force.
Torque does not depend on the distance from the pivot point.
Can you name a tool that uses torque?
Screwdriver
Torque wrench
Pliers
Hammer
Why is understanding torque important in engineering?
Torque is important in engineering for ensuring safety, performance, and efficiency of mechanical systems.
Torque has no impact on the lifespan of machinery.
Understanding torque is unnecessary for mechanical design.
Torque is only relevant in electrical engineering.
