IPC Unit 4a Motion & Force

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What does a distance vs. time graph represent?

Back

A distance vs. time graph shows how the distance of an object changes over time, indicating its speed.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What does a flat line on a distance vs. time graph indicate?

Back

A flat line indicates that the object is stationary (not moving).

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a steeper slope on a distance vs. time graph indicate?

Back

A steeper slope indicates a higher speed.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does it mean if an object is accelerating?

Back

If an object is accelerating, it is changing its velocity, which can mean speeding up, slowing down, or changing direction.

Front

What is a force?

Back

A force is a push or pull acting on an object, which can cause it to accelerate.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
