Physics 11: Kinematics Review

Front

What is the formula to calculate hang time for an object thrown vertically?

Back

Hang time (T) can be calculated using the formula T = 2 * (initial velocity / acceleration due to gravity).

Front

What is the initial velocity of a hacky sack thrown into the air if it has a hang time of 0.61 seconds?

Back

The initial velocity is approximately 3 m/s.

Front

How do you calculate the total distance traveled by an object moving in multiple directions?

Back

Total distance is the sum of all individual distances traveled, regardless of direction.

Front

If Scott travels north 5 miles, west 3 miles, and then south 2 miles, what is his total distance traveled?

Back

Scott's total distance traveled is 10 miles.

Front

What is the relationship between the initial velocity of an object and its maximum height when thrown vertically?

Back

The maximum height is proportional to the square of the initial velocity (H ∝ v^2).

Front

If Ball A is thrown upward with 3 times the velocity of Ball B, how much higher will Ball A go compared to Ball B?

Back

Ball A will reach a maximum height 9 times higher than Ball B.

What happens to the speed of an object at its highest point when thrown vertically?

Back

The speed of the object is zero at its highest point.

Front

What is the acceleration of an object at its highest point when thrown vertically?

Back

The acceleration is not zero; it is equal to the acceleration due to gravity (approximately 9.81 m/s² downward).

Front

How does air resistance affect the time taken for an object to rise and fall?

Back

Air resistance causes the object to take longer to rise than to fall back down.

Front

What is the SI unit for measuring length or distance?

Back

The SI unit for length or distance is the meter (m).
