Force and Motion

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is usually expressed in units like meters per second (m/s) or miles per hour (mi/hr).

Front

What units are typically used on the vertical axis of a distance/time graph?

Back

Meters (m) are typically used on the vertical axis of a distance/time graph.

Front

What is a force?

Back

A force is any push or pull on an object that can cause it to change its velocity (speed or direction).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is calculated as the change in velocity divided by the time taken for that change.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time taken.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What is the relationship between force and motion?

Back

Force causes an object to move or change its motion. According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

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 at a constant velocity unless acted upon by a net external force.

Front

What is the effect of gravity on motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion. On Earth, it causes objects to fall towards the ground.
