Forces and interactions review

Front

A 5 kg object is moving at 5 m/s. What is its momentum?

Back

25 kg * m/s

Front

How could you demonstrate momentum?

Back

2 ice skaters push off each other in opposite directions

Front

What is the overall force acting on an object when all individual forces are combined?

Back

net force

Front

When the mass of an object is doubled while the net force acting on it stays the same, what happens to the object’s acceleration?

Back

it's halved

Front

When an object is accelerating at a constant rate, what happens to the net force if the mass of the object is increased?

Back

net force increases

Front

If there's 0 net force on a system, what happens to the momentum?

Back

momentum stays the same

Front

What is the main goal of designing a device to minimize the force on an object during a collision?

Back

increase time of collision

Front

What happens to the force experienced when the time of a collision is increased?

Back

force decreases

Front

How do you solve for total momentum?

Back

p=(mv)+(mv)

Front

How can you create a magnetic field using an electric current?

Back

coil of wire and battery
