What is the formula to calculate the time an object is in the air when thrown horizontally?

Back

Front

If a rock is thrown horizontally with a velocity of 20 m/s and lands 60 m away, how long is it in the air?

Back

3 s

Front

What is the formula to calculate the velocity of an object given the distance and time?

Back

Front

If a marble rolls off a table horizontally and is in the air for 0.53 s, what velocity is needed to hit a target 4 m away?

Back

7.5 m/s

Front

What does it mean when potential energy (PE) and kinetic energy (KE) are equal at a point in motion?

Back

It indicates that the object has converted some of its potential energy into kinetic energy.

Front

In circular motion, what direction does centripetal acceleration act?

Back

Towards the center of the circle.

Front

In circular motion, what direction does tangential velocity act?

Back

Perpendicular to the circle.

Front

What is the definition of centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path.

Front

What is the definition of tangential velocity?

Back

Tangential velocity is the linear speed of an object moving along a circular path, measured at any point along the path.

Front

What happens to the potential energy of an object as it falls?

Back

The potential energy decreases while kinetic energy increases.
