What is Newtons First law of motion?
200
The tendency of an object to resist change in acceleration.
What is inertia?
200
The basic formula to find Velocity.

The average acceleration as a shuttle bus comes to a normal stop, it slows from 9.00m/s to 0.00m/s in 5.00s.
What is 1.8m/s^2 (or -1.8m/s^2)?
300
A type of elevator called a cage is used to raise and lower miners in a mine shaft. Suppose the cage carries a group of miners down the shaft. If the unbalanced force on the cage is 60.0 N, and the mass of the loaded cage is 150 Kg, what is the acceleration of the cage?
What is 2.5m/s^2?
300
for every action there is an equal and opposite reaction.
What is Newtons third law of motion?
400
Causes an object to accelerate.
What is a Net Force?
400
How fast Alex rode his bicycle if he went 60 kilometers in 4 hours.
What is 15km/h or 250m/s
400
the sprinter’s average acceleration if during a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25s.
What is 2m/s^2?
400
The whale shark is the largest of all fish and can have the mass of three adult elephants. Suppose that a crane is lifting a whale shark into a tank for delivery to an aquarium. The crane must exert an unbalanced force of 25,000 N to lift the shark from rest. If the shark’s acceleration equals 1.25 m/s2, what is the shark’s mass?

The velocity of the stroller after it has traveled for 4.75 minutes if a baby sitter pushing a stroller starts from rest and accelerates at a rate of 0.500m/s^2.
What is 142m/s?
500
In drag racing, acceleration is more important than speed, and therefore drag racers are designed to provide high accelerations. Suppose a drag racer has a mass of 1250 Kg and accelerates at a rate of 16.5 m/s2 . How large is the unbalanced force acting on the racer?
