Exploring Force, Momentum, and Torque

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.
