Force & Motion

Front

What is a PUSH or PULL of an object?

Back

Force

Front

What is the effect of friction on motion?

Back

Friction opposes motion, making it harder to move objects.

Front

Which surface has the most friction: a road, carpet, an ice skating rink, or astro turf?

Back

Carpet has the most friction.

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

If a train travels 100 meters in 10 seconds, how fast is it moving?

Back

10 meters per second.

Front

What happens to the force needed to move a wheelbarrow if half of the rocks are unloaded?

Back

Mass is decreased, making the wheelbarrow easier to move.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, like the Earth pulling us down.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object.

Front

What is the relationship between mass and force?

Back

More mass requires more force to move.
