What is acceleration?
The rate at which velocity changes.
What is displacement?
The distance between the initial position and the final position.
What is the difference between vector and scalar?
Scalar has only magnitude and vector has both magnitude as well as direction.
Define velocity.
Speed in a given direction.
What is the formula for acceleration?
Matt is at a rest stop, and then drives north for 30 miles. What is Matt's displacement.
30 miles
Is the following a scalar or vector quantity and why?
4 m
Scalar because there is no direction.
Is velocity a scalar or vector quantity?
Vector
A dog goes from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s acceleration?
2 m/s2
A cat is at rest, and then chases a ball to the right at 10 feet, then runs back 5 feet to the left. What is the cat's displacement?
5 feet
List three types of vector quantities.
Velocity, Displacement, & Acceleration.
A car travels 15 miles South in 0.5 hours. What's the velocity?
30 m/hr
A roller coaster rapidly picks up speed as it rolls down a slope. As it starts, its speed is 25 m/s. But 60 seconds later, at the bottom of the slope, its speed is 350 m/s. What is its average acceleration?
5.4 m/s2
