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

What is the net force when one person exerts 45 N to the left and another exerts 32 N to the right?

Back

The net force is 13 N to the left.

Front

What does a motion graph that shows a horizontal line indicate?

Back

The object is at rest.

Front

If a soccer ball experiences a net force of 50 N to the left, what does this mean?

Back

The soccer ball is being pushed with a force of 50 N towards the left.

Front

What two factors does gravity between two objects depend on?

Back

The gravity depends on the mass of the objects and the distance between them.

Front

Define inertia.

Back

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

Front

What is the formula for calculating net force?

Back

Net force = Force applied - Force opposing.

Front

Explain the concept of acceleration.

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.
