Science Force and Motion Review

Front

What is the relationship between the height from which an object is dropped and the distance it falls?

Back

The total distance fallen will increase over time as the height from which the object is dropped increases.

Front

How can we compare the speeds of two different animals?

Back

By analyzing their movement over a specific distance and time, we can determine which animal is traveling faster.

Front

What factors influence the outcome of a chase between a photographer and a rhino?

Back

The speed of the photographer, the speed of the rhino, and the distance to safety (the Jeep) are key factors.

Front

Define a pendulum in the context of physics.

Back

A pendulum is a mass hanging from a fixed point that is free to swing to and from.

Front

How do you estimate the speed of an object based on distance and time?

Back

Speed can be estimated by dividing the distance traveled by the time taken to travel that distance.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is gravitational acceleration, and how does it affect falling objects?

Back

Gravitational acceleration is the acceleration of an object due to gravity, approximately 9.81 m/s² on Earth, causing objects to fall faster over time.

Front

What is the concept of inertia in relation to motion?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning an object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force.

Front

How does mass affect the motion of an object?

Back

The mass of an object affects its acceleration when a force is applied; heavier objects require more force to achieve the same acceleration as lighter objects.

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.
