Force and Motion

Front

What happens to a moving object when an unbalanced force acts on it?

Back

The object will accelerate in the direction of the force.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the average speed of a train that travels 200 miles in 4 hours?

Back

50 miles/hour.

Front

What is a force that opposes motion?

Back

Friction.

Front

What force keeps satellites in orbit around Earth?

Back

Gravity.

Front

What type of forces are present in a tug of war game?

Back

Unbalanced forces.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).
