Physics - Semester 1 Test

Front

What is a Position vs Time Graph?

Back

A graphical representation showing the position of an object over time, illustrating how far an object has moved from its starting point.

Front

Define Acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is Velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is Displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

Explain the concept of free fall.

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What happens to the velocity of an object thrown upwards at its highest point?

Back

At the highest point, the velocity of the object is zero before it starts to fall back down.

Front

How does air resistance affect the motion of falling objects?

Back

Air resistance opposes the motion of falling objects, causing them to fall slower than they would in a vacuum.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the significance of the slope in a Position vs Time Graph?

Back

The slope of a Position vs Time Graph represents the velocity of the object; a steeper slope indicates a higher velocity.
