Motion Basics
This quantity describes how fast an object is moving without direction.
What is speed?
This law explains why objects resist changes in motion.
What is Newton’s First Law?
This quantity is calculated by multiplying mass and velocity.
What is momentum?
This is the energy of motion.
What is kinetic energy?
Identify the correct equation used to calculate acceleration from velocity and time.
What is a = Δv / Δt?
This quantity describes how fast an object is moving with direction.
What is velocity?
This law states that acceleration depends on mass and net force.
What is Newton’s Second Law?
This principle states that total momentum remains constant in a closed system.
What is the conservation of momentum?
This is the energy stored due to height above Earth.
What is gravitational potential energy?
An object’s mass doubles while net force stays the same. According to the equation, what happens to acceleration?
What is acceleration is cut in half (from a = F / m)?
This is the rate at which velocity changes.
What is acceleration?
This law explains why forces come in equal and opposite pairs.
What is Newton’s Third Law?
In this type of collision, objects stick together after impact.
What is an inelastic collision?
This quantity measures how quickly work is done.
What is power?
Which equation would you use to calculate momentum before and after a collision?
What is p = mv?
An object travels 20 m in 4 s. Identify the quantity calculated
What is speed?
A shopping cart accelerates more when empty than when full under the same push. Identify the law and equation involved.
What is Newton’s Second Law and F=ma?
A 2 kg cart moving at 3 m/s collides with a stationary cart. Write the equation used to analyze the collision.
What is m1v1+m2v2=m1v1′+m2v2′
Identify the correct equation to calculate gravitational potential energy.
What is PE=mgh?
You know the work done on an object and the time it took. Which equation allows you to calculate power?
What is P = W / t?
An object moves east, slows down, but never changes direction. Which motion quantities are changing?
What are speed and velocity?
If net force is zero, describe the possible motions of an object according to Newton’s laws.
What is constant velocity or rest?
Momentum is conserved in collisions even when kinetic energy is not. What type of collision does this describe?
What is an inelastic collision?
An object is lifted at constant speed. Compare the work done to the change in kinetic energy.
What is work is done but kinetic energy does not change?
A cart’s speed triples. Using an equation, determine how its kinetic energy changes.
What is kinetic energy increases by a factor of 9 (from KE = 1/2 mv²)?
