Force and Motion

Front

What happens to passengers in a car that suddenly stops while traveling at high speed?

Back

Passengers will continue to move in a straight line and will slide forward in the car due to inertia.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

If a man and a ball travel 90 meters in 9 seconds, what is their average speed?

Back

10 m/s (Average speed = Distance/Time = 90m/9s).

Front

What unit is typically placed on the vertical axis of a distance/time graph?

Back

Meters.

Front

What is the force that opposes motion?

Back

Friction.

Front

Define inertia in the context of motion.

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 formula for calculating force?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the difference between speed and velocity?

Back

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